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. Perhaps macvtap is what you want: http://virt.kernelnewbies.org/MacVTap http://wiki.math.cmu.edu/iki/wiki/tips/20140303-kvm-macvtap.html Stefan
