Dan, Yaniv, any reason for not explicitly requiring the updated version of libvirt in VDSM package? If it's just because libvirt is not yet in official Fedora repository, maybe we should ship it on ovirt repository until it's in and put some pressure on libvirt people for having them pushing the newest package into Fedora. Thoughts?
