XenServer 6 introduced the ability to create multi-VM and boot sequenced virtual appliances (vApps) that integrate with Integrated Site Recovery and High Availability. vApps can be easily imported and exported using the Open Virtualization Format (OVF) standard. There is full support for VM disk and OVF appliance imports directly from XenCenter with the ability to change VM parameters (virtual processor, virtual memory, virtual interfaces, and target storage repository) with the Import wizard. Full OVF import support for XenServer, XenConvert and VMware.
