Detailed Description
virt-v2v is a command line tool that enables Xen domUs (ie. guests) to be migrated to use KVM. Usage will be: virt-v2v xen_domain -o kvm_domain

(for a libvirt-managed domain called ).

The process will automatically install the correct kernel and driver(s) and make any configuration changes necessary so that the KVM domain will run with virtio drivers.

The process will also be reversible - if the KVM transition doesn't work out, then system administrators can go back to the original, untouched Xen domain, via a snapshot.

Benefit to Fedora
Users with Xen guests can try out KVM. Users can also migrate from Xen to KVM for its enhanced ease of use.
