According to http://libvirt.org/hvsupport.html, no one has ported any of the virDomainMigrate callbacks to the openvz driver. > If yes, please let me know the correct way to do that.

The plan is to wait for someone to submit a patch. So go for it! You can use qemu and libxl migration code as a guide when implementing the callbacks in the openvz code. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
