[libvirt-users] Live migration: Xen to KVM
Hello! Is there some way to migrate guest OS from one Xen-host to another KVM-host using libvirt? (live migration is highly desirable) (Both hosts have the same hardware, Xen running in full-virtualized mode.)

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. That's why it can only be done offline. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
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? 2013/2/5 Eric Blake <eblake@redhat.com>
