RHV 4.1 released in April 2017
NEW
RHV 4.1 is the 11th major release of Red Hats enterprise virtualization management software based on the KVM hypervisor.
In 2008 Red Hat acquired Qumranet, a technology startup that began the development of KVM. Red Hats first release of RHV was v2.1 in 2009. The v3.0 release in 2012 was a major milestone in porting the RHV-M manager from .NET to Java (and fully open-sourcing). RHV 3.1 removed all requirements of any Windows-based infrastructure, but still support Microsoft Active Directory and guests. Since RHV 3.2, Red Hat has provided many feature enhancements, improvements in scale, enhanced reliability and integration points to other Red Hat offerings based on the cutting edge KVM developement.

- Cross vCenter vMotion (n/a for Standard)
- Long Distance vMotion (n/a for Standard)
- Cross Cloud vMotion (n/a for Standard)
- Encryption vMotion (n/a for Standard)
|
Yes
Each cluster is configured with a minimal CPU type that all hosts in that cluster must support (you specify the CPU type in the RHV-M GUI when creating the cluster). Guests running on hosts within the cluster all run on this CPU type, ensuring that every guest can be live migrated to any host within the cluster. This cannot be changed after creation without significant disruption. All hosts in a cluster must run the same CPU type (Intel or AMD).
|
|
|
Migration Compatibility
Details
|
=AU27
|
Yes (EVC)
EVC can be enabled Per-VM (new)
Enhanced vMotion Compatibility - enabled on vCenter cluster-level, utilizes Intel FlexMigration or AMD-V Extended Migration functionality available with most newer CPUs (but cannot migrate between Intel and AMD), Details here: http://kb.vmware.com/kb/1005764
|
Yes
|
|
|
|
=AU28
|
Yes
Maintenance mode is a core feature to prepare a host to be shut down safely.
vSphere Quick Boot is a new innovation that restarts the ESXi hypervisor without rebooting the physical host. (new)
|
Yes - Built-in (CPU\Memory) and plugable scheduler
A policy engine determines the specific host on which a virtual machine runs. The policy engine decides which server will host the next virtual machine based on whether load balancing criteria have been defined, and which policy is being used for that cluster. RHV-M will use live migration to move virtual machines around the cluster as required.
A scheduler handles virtual machine placement, allowing users to create new scheduling policies, and also write their own logic in Python and include it in a policy.
- The scheduler serves scheduling requests for running or migrating virtual machines according to a policy.
- The scheduling policy also includes load balancing functionality.
- Scheduling is performed by applying hard constraints and soft constraints to get the optimal host for that request at a given point of time
- The infrastructure allowing users to extend the new scheduler, is based on a service called ovirt-scheduler-proxy. The services purpose is for RHV admins to extend the scheduling process with custom python filters, weight functions and load balancing modules.
- Every cluster has a scheduling policy. Administrators can create their own policies or use the built-in policies which were extended to support new capabilities such as shutting down servers for power saving policy.
The load balancing process runs once every minute for each cluster in a data center. You can disable automatic migration for individual vm or pin them to specific hosts.
You can choose to set the policy as either even distribution or power saving, but NOT both.
|
|
|
Automated Live Migration
Details
|
=AU29
|
Yes (DRS) - CPU, Mem
VM Distribution: Enforce an even distribution of VMs.
Memory Metric for Load Balancing: DRS uses Active memory + 25% as its primary metric.
CPU over-commitment: This is an option to enforce a maximum vCPU:pCPU ratios in the cluster.
Network Aware DRS - system look at the network bandwidth on the host when considering making migration recommendations.
Storage IO Control configuration is now performed using Storage Policies and IO limits enforced using vSphere APIs for IO Filtering (VAIO).
Storage Based Policy Management (SPBM) framework, administrators can define different policies with different IO limits, and then assign VMs to those policies.
|
Yes
When Power saving is enabled in a cluster it distributes the load in a way that consolidates virtual machines on a subset of available hosts. This enables surplus hosts that are not in use to be powered down, saving power. You can set the threasholds in the RHV-M GUI to specify the Minimum Service Level a host is permitted to have.
You must also specify the time interval in minutes that a host is permitted to run below the minimum service level before remaining virtual machines are migrated to other hosts in the cluster - as long as the maximum service level set also permits this.
|
|
|
|
=AU30
|
Yes (DPM)
Distributed Power Management - enables to consolidate virtual machines onto fewer hosts and power down unused capacity - reducing power and cooling. This can be fully automated where servers are powered off when not needed and powered back on when workload increases.
|
Yes
Storage Live Migration is supported and allows migration of virtual machine disks to different storage devices while the virtual machine is running. There is also an option to move an entire storage domain between datacenters or even between setups.
|
|
|
Storage Migration
Details
|
=AU31
|
Yes (Live Storage vMotion)
Storage vMotion allows to perform live migration of virtual machine disk files (e.g. across heterogeneous storage arrays) without vm downtime. Storage DRS handles initial vmdk placement and gives migration recommendations to avoid I/O and space utilization bottlenecks on the datastores in the cluster. The migration is performed using storage vMotion.
|
200 hosts/cluster
That is the supported maximum number of hosts per RHV datacenter and also per cluster (the theoretical KVM limit is higher).
|
|
|
|
HA/DR |
|
|
|
|
=AU32
|
max 64 nodes / 8000 vm per cluster
Up to 64 nodes can be in a DRS/HA cluster, with a maximum of 8000 vm/cluster
|
Yes
High availability is an integrated feature of RHV and allows for virtual machines to be restarted in case of a host failure.
HA has to be enabled on a virtual machine level. You can specify levels of priority for the vm (e.g. if resources are restrained only high priority vm are being restarted). Hosts that run highly available vm have to be configured for power management (to ensure accurate fencing in case of host failure).
Fencing Details: When a host becomes non-responsive it potentially retains the lock on the virtual disk images for virtual machines it is running. Attempting to start a virtual machine on a second host could cause data corruption. Fencing allows RHV-M to safely release the lock (using a fence agent that communicates with the power management card of the host) to confirm that a problem host has truly been rebooted.
RHV-M gives a non-responsive host a grace period of 30 seconds before any action is taken in order to allow the host to recover from any temporary errors.
Note: The RHV-M manager needs to be running for HA to function (unlike e.g. VMware HA or Hyper-V HA that do not rely on vCenter / VMM for the failover capability), also HA can not be enabled on the cluster level.

Integrated HA (Restart vm)
Details
|
=AU33
|
Yes (VMware HA)
vSphere 6.5 Proactive HA detect hw condition evacuate host before failure (plugin provided OEM vendors)
Quarantine mode - host is placed in quarantine mode if it is considered in degraded state
Simplified vSphere HA Admission Control - 'Percentage of Cluster Resources' admission control policy
vSphere 6.0
- Support for Virtual Volumes – With Virtual Volumes a new type of storage entity is introduced in vSphere 6.0.
- VM Component Protection – This allows HA to respond to a scenario where the connection to the virtual machine’s datastore is impacted temporarily or permanently.
“Response for Datastore with All Paths Down”
“Response for Datastore with Permanent Device Loss”
- Increased scale – Cluster limit has grown from 32 to 64 hosts and to a max of 8000 VMs per cluster
- Registration of “HA Disabled” VMs on hosts after failure.
VMware HA restarts virtual machines according to defined restart priorities and monitors capacity needs required for defined level of failover.
vSphere HA in vSphere 5.5 has been enhanced to conform with virtual machine-virtual machine anti-affinity rules. Application availability is maintained by controlling the placement of virtual machines recovered by vSphere HA without migration. This capability is configured as an advanced option in vSphere 5.5.
vSphere 5.5 also improved the support for virtual Microsoft Failover Clustering (cluster nodes in virtual machines) - note that this functionality is independent of VMware HA and requires the appropriate Microsoft OS license and configuration of a Microsoft Failover Cluster. Microsoft clusters running on vSphere 5.5 now support Microsoft Windows Server 2012, round-robin path policy for shared storage, and iSCSI and Fibre Channel over Ethernet (FCoE) for shared storage.
While not obvious to the user - with vSphere 5, HA has been re-written from ground-up, greatly reducing configuration and failover time. It now uses a one master - all other slaves concept. HA now also uses storage path monitoring to determine host health and state (e.g. useful for stretched cluster configurations).
|
Yes (HA, WatchDog)
RHV supports watchdog device for linux guests that restarts virtual machines in case of OS failure. High availability (in addition to monitoring physical hosts) also monitors all virtual machines, so if the virtual machines operating system crashes, a signal is sent to automatically restart the virtual machine, but this is with host change.
|
|
|
Automatic VM Reset
Details
|
=AU34
|
Yes (VMware HA)
vSphere 6.5 - Orchestrated Restart - VMware has enforced the VM to VM dependency chain, for a multi-tier application installed across multiple VMs.
Uses heartbeat monitoring to reset unresponsive virtual machines.
|
No
There is no live lock-step mirroring support in RHV - although the theoretical capability is available in KVM. Red Hat tends to points out that the limitations around this technology (inability to take e.g. snap shots, perform a live storage migrate, limited guest vCPU support, high bandwidth/processing requirements) can make it inappropriate for enterprise implementation.
|
|
|
VM Lockstep Protection

Virtual and Physical
Details
|
=AU21
|
Limited (plug-ins)
vCenter and associated components focus on management of virtual infrastructure - physical (non-virtualized) infrastructure will typically require separate management.
However, one can argue that there are increasingly aspects of physical management (bare metal host deploy, vCenter Operations capabilities, vCenter monitoring of physical hosts etc. but the core focusses on the virtual aspects).
Additionally, VMware encourages 3rd party vendors to provide management plug-ins for the vCenter Client (classic or web) that can manage peripheral components of the environment (3rd party storage, servers etc.).

Yes (Storage Based Policy Management)
Using the Storage Based Policy Management (SPBM) framework, administrators can define different policies with different IO limits, and then assign VMs to those policies. This simplifies the ability to offer varying tiers of storage services and provides the ability to validate policy compliance.
The policy-driven control plane is the management layer of the VMware software-defined storage model, which automates storage operations through a standardized approach that spans across the heterogeneous tiers of storage in the virtual data plane.
Storage Policy-Based Management (SPBM) is VMware’s implementation of the policy-driven control plane which provides common management over:
- vSphere Virtual Volumes - external storage (SAN/NAS)
- Virtual SAN – x86 server storage
- Hypervisor-based data services – vSphere Replication or third-party solutions enabled by the vSphere APIs for IO Filtering.
|
Yes
RHV includes quota support and service level agreement (SLA) for storage I/O bandwidth, network interfaces and CPU QoS\shares:
- Quota provides a way for the Administrator to limit the resource usage in the System. Quota provides the administrator a logic mechanism for managing resources allocation for users and groups in the Data Center. This mechanism allows the administrator to manage, share and monitor the resources in the Data Center from the engine core point of view.
- vNIC profile allows the user to limit the inbound and outbound network traffic in virtual NIC level.
- CPU profile limits the CPU usage of a virtual machine.
- Disk profile limit the bandwidth usage to allocate the bandwidth in a better way on limited connections.
- CPU shares is a user defined number that represent a relative metric for allocating CPU capacity. It defines how often a virtual machine will get a time slice of a CPU when there is no CPU idle time.
- Host network QoS can define limits on network usage on the pysical NIC.

sVirt, SELinux, iptables, VLANs, Port Mirroring
The RHV Hypervisor has various security features enabled. Security Enhanced Linux (SELinux) and the iptables firewall are fully configured and on by default. SELinux and sVirt adds security policy in kernel for effective intrusion detection, isolation and containment (SELinux is essentially a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible mandatory access control architecture into the major subsystems of the kernel. e.g. with SELinux you can give each qemu process a different SELinux label to prevent a compromised qemu from attacking other processes and also allows you to label the set of resources that each process can see , so that a compromised qemu can only attack its own disk images).
Advanced network security features like VLAN tagging and port mirroring are part of RHV, but there are no additional security-specific add-ons included with RHV (e.g. to address advanced fire-walling, edge security capabilities or Anti-Virus APIs).

Yes (FC, FCoE, iSCSI)
NEW
Multipathing in RHV manager provides:
1) Redundancy (provides failover protection).
2) Improved Performance which spreads I/O operations over the paths, by default in a round-robin fashion but also supports other methods including Asynchronous Logical Unit Access (ALUA). This applies to block devices (FC, FCoE, iSCSI), although the equivalent functionality can be achieved with a sufficiently robust network setup for network attached storage.
|
|
|
|
=AU66
|
Yes (enhanced APD and PDL) PDL AutoRemove
vSphere uses natively integrated multi-path capability or can take advantage of vendor specific capabilities using vStorage APIs for Multipathing.
By default, ESXi provides an extensible multipathing module called the Native Multipathing Plug-In (NMP). Generally, the VMware NMP supports all storage arrays listed on the VMware storage HCL and provides a default path selection algorithm based on the array type. The NMP associates a set of physical paths with a specific storage device, or LUN. The specific details of handling path failover for a given storage array are delegated to a Storage Array Type Plug-In (SATP). The specific details for determining which physical path is used to issue an I/O request to a storage device are handled by a Path Selection Plug-In (PSP). SATPs and PSPs are sub plug-ins within the NMP module. With ESXi, the appropriate SATP for an array you use will be installed automatically. You do not need to obtain or download any SATPs.
PDL AutoRemove: Permanent device loss (PDL) is a situation that can occur when a disk device either fails or is removed from the vSphere host in an uncontrolled fashion. PDL detects if a disk device has been permanently removed. When the device enters this PDL state, the vSphere host can take action to prevent directing any further, unnecessary I/O to this device. With vSphere 5.5, a new feature called PDL AutoRemove is introduced. This feature automatically removes a device from a host when it enters a PDL state.

RAW, Qcow2
RHV supports two storage formats: RAW and QCOW2.
In an NFS data center the Storage Pool manager (SPM) creates the virtual disk on top of a regular file system as a normal disk in preallocated (RAW) format. Where sparse allocation is chosen additional layers on the disk will be created in thinly provisioned Qcow2 (sparse) format.
For iSCSI and SAN (block), the SPM creates a Volume group (VG) on top of the Logical Unit Numbers (LUNs) provided. During the virtual disk creation, either a preallocated format (RAW) or a thinly provisioned Qcow2 (sparse) format is created.
Background:
QCOW (QEMU copy on write) decouples the physical storage layer from the virtual layer by adding a mapping between logical and physical blocks. This enables advanced features like snapshots. Creating a new snapshot creates a new copy on write layer, either a new file or logical volume, with an initial mapping that points all logical blocks to the offsets in the backing file or volume. When writing to a QCOW2 volume, the relevant block is read from the backing volume, modified with the new information and written into the new snapshot QCOW2 volume. T hen the map is updated to point to the new place.
Benefits QCOW2 offers over using RAW representation include:
- Copy-on-write support (volume only represents changes to a disk image).
- Snapshot support (volume can represent multiple snapshots of the images history).
The RAW storage format has a performance advantage over QCOW2 as no formatting is applied to images stored in the RAW format (reading and writing images stored in RAW requires no additional mapping or reformatting work on the host or manager. When the guest file system writes to a given offset in its virtual disk, the I/O will be written to the same offset on the backing file or logical volume. Note: Raw format requires that the entire space of the defined image be preallocated (unless using externally managed thin provisioned LUNs from a storage array).
A virtual disk with a preallocated (RAW) format has significantly faster write speeds than a virtual disk with a thin provisioning (Qcow2) format. Thin provisioning takes significantly less time to create a virtual disk. The thin provision format is suitable for non-IO intensive virtual machines.
|
|
|
Virtual Disk Format
Details
|
=AU70
|
vmdk, raw disk (RDM)
VMware Virtual Machine Disk Format (vmdk) and RAW Disk Mapping (RDM) - essentially a raw disk mapped to a proxy (making it appear like a VMFS file system)
|
Default max virtual disk size is 8TB (but its configurable in RHV DB)
The default maximum supported virtual disk size is 8TB in RHV (but its configurable in RHV DB).
With virtio-scsi support, Red Hat also supports now 16384 logical units per target.
File level disk size remains unlimited by the hypervisor, the limits of the underlying filesystem do however apply.
|
|
|
|
=AU71
|
64TB
vSphere is increasing the maximum size of a virtual machine disk file (VMDK) from 2TB - 512 bytes to the new limit of 64TB. The maximum size of a virtual Raw Device Mapping (RDM) is also increasing, from 2TB - 512 bytes to 64TB in physical compatibility and 62TB in virtual compatibility. Virtual machine snapshots also support this new size for delta disks that are created when a snapshot is taken of the virtual machine.
|
Yes
During the virtual disk creation, either a preallocated format (RAW) or a thinly provisioned Qcow2 (sparse) format can be specified.
A preallocated virtual disk has reserved storage of the same size as the virtual disk itself. The backing storage device (file/block device) is presented as is to the virtual machine with no additional layering in between. This results in better performance because no storage allocation is required during runtime. On SAN (iSCSI, FCP) this is achieved by creating a block device with the same size as the virtual disk. On NFS this is achieved by filling the backing hard disk image file with zeros. Pre-allocating storage on an NFS storage domain presumes that the backing storage is not Qcow2 formatted and zeroes will not be deduplicated in the hard disk image file. (If these assumptions are incorrect, do not select Preallocated for NFS virtual disks).
For sparse virtual disks backing storage is not reserved and is allocated as needed during runtime. This allows for storage over commitment under the assumption that most disks are not fully utilized and storage capacity can be utilized better. This requires the backing storage to monitor write requests and can cause some performance issues. On NFS backing storage is achieved simply by using files. On SAN this is achieved by creating a block device smaller than the virtual disks defined size and communicating with the hypervisor to monitor necessary allocations. This does not require support from the underlying storage devices.

|
=AU73
|
Yes (RDM only)
NPIV requires RDM (Raw Disk Mapping), it is not supported with VMFS volumes. NPIV requires supported switches (not direct storage attach).
|
Yes
In RHV by default, virtual machines created from templates use thin provisioning. In the context of templates, thin provisioning of vm means copy on write (aka linked clone or difference disk) rather than a growing file system that only takes up the storage space that it actually uses (usually referred to as thin provisioning). All virtual machines based on a given template share the same base image as the template and must remain on the same data domain as the template.
You can however specify to deploy the vm from template as clone - which means that a full copy of the vm will be deployed. When selecting to clone you can then select thin (sparse) or pre-allocated provisioning of the full clone. Deploying from template as clone results in independence from the base image but space savings associated with using copy on write approaches are lost.
A virtual disk with a preallocated (RAW) format has significantly faster write speeds than a virtual disk with a thin provisioning (Qcow2) format. Thin provisioning takes significantly less time to create a virtual disk. The thin provision format is suitable for non-IO intensive virtual machines.

Yes (vSphere Flash Read Cache)
vSphere 5.5 introduced the vSphere Flash Read Cache that enables the pooling of multiple Flash-based devices into a single consumable vSphere construct called vSphere Flash Resource.
vSphere hosts can use the vSphere Flash Resource as vSphere Flash Swap Cache, which replaces the Swap to SSD feature previously introduced with vSphere 5.0. It provides a write-through cache mode that enhances virtual machines performance without the modification of applications and OSs.
At its core Flash Cache enables the offload of READ I/O from the shared storage to local SSDs, reducing the overall I/O requirements on your shared storage.
Documented maxima with vSphere 6.5:
- Virtual flash resource per host: 1
- Maximum cache for each virtual disk: 400GB
- Cumulative cache configured per host (for all virtual disks): 2TB
- Virtual disk size: 16TB

Advanced Network Switch
Details
|
=AU80
|
Yes (vDS)
vSphere Distributed Switch (VDS) spans multiple vSphere hosts and aggregates networking to a centralized datacenter-wide level, simplifying overall network management (rather than managing switches on individual host level) allowing e.g. the port state/setting to follow the vm during a vMotion (Network vMotion) and facilitates various other advanced networking functions - including 3rd party virtual switch integration.
Each vCenter Server instance can support up to 128 VDSs, each VDS can manage up to 2000 hosts.
|
Yes
RHV support 4 bonding modes with easy management of their definition on the host.
Details:
Mode 1 (active-backup policy) sets all interfaces to the backup state while one remains active. Upon failure on the active interface, a backup interface replaces it as the only active interface in the bond. The MAC address of the bond in mode 1 is visible on only one port (the network adapter), to prevent confusion for the switch. Mode 1 provides fault tolerance and is supported in Red Hat Virtualization.
Mode 2 (XOR policy) selects an interface to transmit packages to based on the result of an XOR operation on the source and destination MAC addresses multiplied by the modulo slave count. This calculation ensures that the same interface is selected for each destination MAC address used.
Mode 2 provides fault tolerance and load balancing and is supported in Red Hat Virtualization.
Mode 4 (IEEE 802.3ad policy) creates aggregation groups for which included interfaces share the speed and duplex settings. Mode 4 uses all interfaces in the active aggregation group in accordance with the IEEE 802.3ad specification and is supported in Red Hat Virtualization.
Mode 5 (adaptive transmit load balancing policy) ensures the outgoing traffic distribution is according to the load on each interface and that the current interface receives all incoming traffic. If the interface assigned to receive traffic fails, another interface is assigned the receiving role instead. Mode 5 is
supported in Red Hat Virtualization.
|
|
|
|
=AU81
|
Yes (up to 32 NICs)
vSphere has integrated NIC teaming capabilities. To utilize NIC teaming, two or more network adapters must be uplinked to a virtual switch (standard or distributed).
The key advantages of NIC teaming are:
- Increased network capacity for the virtual switch hosting the team.
- Passive failover in the event one of the adapters in the team goes down
There are various NIC load balancing (e.g. based on originating port, source MAC or IP hash) and failover detection algorithms (link status, Beacon probing).
|
Yes
With RHV the Network Interfaces tab of the details pane shows VLAN information for the edited network interface. In the VLAN column newly created VLAN devices are shown, with names based on the network interface name and VLAN tag.
Background: RHV VLAN is aware and is able to tag and redirect VLAN traffic, however VLAN implementation requires a switch that supports VLANs.
At the switch level, ports are assigned a VLAN designation. A switch applies a VLAN tag to traffic originating from a particular port, marking the traffic as part of a VLAN, and ensures that responses carry the same VLAN tag. A VLAN can extend across multiple switches. VLAN tagged network traffic on a switch is completely undetectable except by machines connected to a port designated with the correct VLAN. A given port can be tagged into multiple VLANs, which allows traffic from multiple VLANs to be sent to a single port, to be deciphered using software on the machine that receives the traffic.
|
|
|
|
=AU82
|
Yes
Support for VLANs, VLAN tagging with distributed or standard switch. Private VLANs (sub-VLANs) are supported with the virtual distributed switch only
|
Yes (via host hooks)
Currently PVLAN support in RHV is done via host hook.
Background: Hooks are scripts executed on the host when key events occur. The creation and use of VDSM hooks to trigger modification of virtual machines based on custom properties specified in the Administration Portal.
|
|
|
|
=AU83
|
Yes
Private VLANs (sub-VLANs) are supported with the virtual distributed switch.
|
Guests fully, hypervisors partially
RHV currently uses IPv4 for internal communications and does not use/support IPv6. Using IPv6 at the virtual machine level is fully supported though, provided that youre using a guest operating system thats compatible.
As of RHV-4.1, RHV can assign IPV6 addresses to host interfaces.
|

|
Yes
vSphere supports jumbo frames for network traffic including iSCSI, NFS, vMotion and FT
|
TOE
Currently, RHV hypervisors support TOE. Due to the way that RHV provides networking access to the virtual machines, using technologies such as TSO/LRO/GRO are currently unsupported. With OVN-based overlay networks (tech-preview in 4.1), a NIC can carry VM traffic while having offloading set.
|
|

Supports TCP Segment Offloading, NetQueue (VMwares implementation of Intels VMDq and iSCSI HW offload (for a limited number of HBAs).
No TOE support (you can use TOE capable adapters in vSphere but the TOE function itself will not be used)
|
Yes (vNIC Profile)
RHV has the ability to control Network QoS using virtual NIC profiles through the RHV-M interface.
Users can limit the inbound and outbound network traffic on a virtual NIC level by applying profiles which define attributes such as port mirroring, quality of service (QoS) or custom properties.
|
|
|
|
=AU88
|
Yes (NetIOC)
vSphere 6.x Network I/O Control (NIOC) Version 3
- Ability to reserve bandwidth at a VMNIC
- Ability to reserve bandwidth at a vSphere Distributed Switch (VDS) Portgroup
Network I/O control enables you to specify quality of service (QoS) for network traffic in your virtualized environment. NetIOC requires the use of a virtual distributed switch (vDS). It allows to prioritize network by traffic type and the creation of custom network resource pools.
|
Yes (Port Mirroring)
RHV has port mirroring capabilities.
It is now possible to configure the virtual Network Interface Card (vNIC) of a virtual machine to run in promiscuous mode. This allows the virtual machine to monitor all traffic to other vNICs exposed by the host on which it runs. Port mirroring copies layer 3 network traffic on given a logical network and host to a virtual interface on a virtual machine. This virtual machine can be used for network debugging and tuning, intrusion detection, and monitoring the behavior of other virtual machines on the same host and logical network.
RHV also adds the ability to create a Virtual Network Interface Controller (VNIC) profile to toggle port monitoring. There are also the vendor-supplied UI plug-ins to RHV-M, e.g. the Nagios community plugin.

Traffic Monitoring
Details
|
=AU89
|
yes (Port Mirroring)
Port mirroring is the capability on a network switch to send a copy of network packets seen on a switch port to a network-monitoring device connected to another switch port. Port mirroring is also referred to as Switch Port Analyzer (SPAN) on Cisco switches. Distributed Switch provides a similar port mirroring capability that is available on a physical network switch. After a port mirror session is configured with a destination -a virtual machine, a vmknic or an uplink port-the Distributed Switch copies packets to the destination.
|
Yes (virtio), Mem Balloon optimization and error messages
The virtio-balloon driver allows guests to express to the hypervisor how much memory they require. The balloon driver allows the host to efficiently allocate and memory to the guest and allow free memory to be allocated to other guests and processes. Guests using the balloon driver can mark sections of the guests RAM as not in use (balloon inflation). The hypervisor can free the memory and use the memory for other host processes or other guests on that host. When the guest requires the freed memory again, the hypervisor can reallocate RAM to the guest (balloon deflation).
This includes:
- Memory balloon optimization (Users can now enable virtio-balloon for memory optimization on clusters. All virtual machines on cluster level 3.2 and higher includes a balloon device, unless specifically removed. When memory balloon optimization is set, MoM will start ballooning to allow memory overcommitment, with the limitation of the guaranteed memory size on each virtual machine.
- Ballooning error messages (When ballooning is enabled for a cluster, appropriate messages now appear in the Events tab)

Virtual Hardware version 14
VMware developed/proprietary bare-metal hypervisor, which with vSphere 5 onwards is only available as ESXi (small foot-print without Console OS). The hypervisor itself is < 150MB. Device drivers are provided with the hypervisor (not with the Console OS or dom0/parent partition as with Xen or Hyper-V technologies).
ESX is based on binary translation (full virtualization) but also uses aspects of para-virtualization (device drivers, VMware tools and the VMI interface for para-virtualization) and supports hardware assisted virtualization aspects.

No limit stated
The RHV Hypervisor is not limited by a fixed technology (or marketed) restriction. Red Hat lists no Limit for the maximum ratio of virtual CPUs per host.
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/chap-Overcommitting_with_KVM.html
In reality the specifications of the underlying hardware, nature of the workload in the vm and the overall restriction of 240 logical CPUs per host will determine the limit. RHV has been publicly demonstrated (see SPECvirt) to run over 550 VMs with a mix of SMP vCPU VMs.

DAS, iSCSI, NFS, GlusterFS, FC, POSIX;
Virtio SCSI support
RHV storage is logically grouped into storage pools, which are comprised of three types of storage domains: data (vm and snapshots) , export (temporary storage repository that is used to copy and move images between data centers and RHV instances), and ISO.
The data storage domain is the only one required by each data center and exclusive to a single data center. Export and ISO domains are optional, but require NFS or POSIX.
Storage domains are shared resources and can be implemented using NFS, GlusterFS, POSIX, iSCSI or the Fibre Channel Protocol (FCP). On NFS, all virtual disks, templates, and snapshots are simple files. On SAN (iSCSI/FCP), block devices are aggregated into a logical entity called a Volume Group (VG). This is done using the Logical Volume Manager (LVM) and presents high performance I/O.
Luns can be directly attached to VMs as disks, but some feature are not supported when this option is used like snapshotting.
Local storage can be used to create non-shared local datacenter which allow a single host.

|
|
Dynamic / Over-Commit
Details
|
=AU90
|
Yes (Memory Ballooning)
vSphere uses several memory optimization techniques, mainly to over-commit memory and reclaim unused memory: Ballooning, memory compression and transparent page sharing. Last level of managing memory overcommit is hypervisor swapping (not desired).
When physical host memory is over-committed (e.g. the host has a total of 128GB of RAM but a total of 196GB are allocated to virtual machines), the memory balloon driver (vmmemctl) collaborates with the server to reclaim pages that are considered least valuable by the guest operating system. When memory is tight (i.e. all virtual machines are requesting their maximum memory allocation to be used), the guest operating system determines which pages to reclaim and, if necessary, swaps them to its own virtual disk.
|
Yes (KSM)
Kernel SamePage Merging (KSM) reduces references to memory pages from multiple identical pages to a single page reference. This helps with optimization for memory density.
|
|
|
Memory Page Sharing
Details
|
=AU91
|
Yes (Transparent Page Sharing)
vSphere uses several memory techniques: Ballooning, memory compression and transparent page sharing. Last level of managing memory overcommit is hypervisor swapping (not desired).
A good example is a scenario where several virtual machines are running instances of the same guest operating system, have the same applications or components loaded, or contain common data. In such cases, a host uses a proprietary transparent page sharing technique to securely eliminate redundant copies of memory pages. As a result, higher levels of over-commitment can be supported.
|
Yes
RHV has a feature called transparent huge pages, where the Linux kernel dynamically creates large memory pages (2MB versus 4KB) for virtual machines, improving performance for VMs that require them (newer OSs generations tend to benefit less from larger pages)

sVirt & Security Partnerships
RHV includes sVirt, a technology included in Red Hat Enterprise Linux 6 that integrates SELinux and virtualization. sVirt applies Mandatory Access Control (MAC) to improve security when using virtual machines. The main reasons for integrating these technologies are to improve security and harden the system against bugs in the hypervisor that might be used as an attack vector aimed toward the host or to another virtual machine. To learn more about sVirt, visit this link: http://red.ht/1oZPMkf. Also Red Hats RHV partner ecosystem has security partnerships with SourceFire, Catbird, and other security-focused products and solutions.
