+Virt-v2v converts guests from one virtualization hypervisor to
+another.  Currently it is limited in what it can convert.  See the

+=head2 CONVERTING XEN DOMAINS
+
+For Xen domains managed by libvirt, perform the initial conversion
+using:
+
+ virt-v2v xen_name -o kvm_name
+
+where C<xen_name> is the libvirt Xen domain name, and C<kvm_name> is
+the (new) name for the converted KVM guest.
+
+Then test boot the new guest in KVM:
+
+ virsh start kvm_name
+ virt-viewer kvm_name
+
+When you have verified that this works, shut down the new KVM domain
+and I<commit> the changes by doing:
+
+ virt-v2v --commit kvm_name
+
+I<This command will destroy the original Xen domain>.
+
+Or you can I<rollback> to the original Xen domain by doing:
+
+ virt-v2v --rollback kvm_name
+
+B<Very important note:> Do I<not> try to run both the original Xen
+domain and the KVM domain at the same time!  This will cause guest
+corruption.
