Virtualized to virtualized migration, known as V2V, is supported in Red Hat Enterprise Linux 6 for certain virtualized guests.

Red Hat Enterprise Linux 6 provides tools for converting virtualized guests from other types of hypervisor to KVM. The virt-v2v tool converts and imports virtual machines from Xen, other versions of KVM and VMware ESX.

For more information on using V2V, refer to Chapter 23, Migrating to KVM from other hypervisors using virt-v2v
