Public bug reported: On Ubuntu 10.04 I have problems using libvirt with a bridge because the TUN devices get random mac addresses and thus, change the bridge device mac address, which takes the lower mac addres of all devices attached to the bridge. The main and most critical problem is that, sometimes, we lose network connectivity for several seconds (usually 10-20 seconds) on the libvirt host and all its guests when a guest is powered off.
