If you modify the guest XML, the /domain/drivers/emulator XPath element can set the path to the KVM executable you want to use for that domain (libvirt fills in that element automatically with the kvm it found by default if you didn't provide it, but by modifying the XML, you can change the path to use on the next boot of the domain). -- Eric Blake   eblake(a)redhat.com    +1-919-301-3266 Libvirt virtualization library http://libvirt.org
