[Bug 579892] [NEW] libvirt should not use the MAC address assigned to tap devices/vnet interfaces by the TAP/TUN driver

[Carlos Perelló Marín]

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.
