Yes macvtap should be a solution, but somehow libvirt can't turn on VM itself afterwards. Any idea? Sent from my BlackBerry 10 smartphone.

Are you deploying KVM and worried about the one-time downtime that might be introduced by setting up a bridged setup on the host? Once you have the bridge working you can add/remove tap interfaces from it without affecting the host's physical interface. I'm not sure I understand the problem.
