[libvirt] virDomanMigrate on kvm fails

[Kenneth Nagin]

virDomainMigrate fails when the domain is a kvm guest.
The error message is "this function is not supported by the hypervisor:
virDomainMigrate."
I tried migrating with virsh but it says it can not connected to the
destination host.
I have successfully created copies of the same image on both  so that is
not the problem.
I hava also booted the same hosts with xen and virDomainMigrate worked.
What do you think the problem is?
