Thanks a lot for answer!
i'll check virt-v2v for offline migration.

Besides you don't give a chance to Live Migr, i have some thoughts on it.

(May be i got the whole thing wrong,)

As i know, Xen uses QUEMU hw-emulators, KVM uses them too.
It seems HW-emulation is quite the same on both systems.

So, why still we have to convert guest-drivers?

Live migration: no.
Offline migration: yes - you may want to check out the virt-v2v project
for this.
http://libguestfs.org/virt-v2v/

Remember, since the two hypervisors present different hardware to the
guest, part of the conversion process is preparing the guest to have
drivers appropriate for the new hypervisor. šThat's why it can only be
done offline.
