We're waiting for a better patch that supports both versions of HyperV at once, for as long as Microsoft supports both versions. Look at the vbox driver code for an example of supporting more than one version at once (although that code may not be the best example, on the other hand, it is the subject of active patches trying to improve it). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
