[libvirt] Set MAC address for host virtual interface?

Hello: Is there a way to set the MAC address for the virtual interface on the host? I have this in my guests's XML file: <interface type='bridge'> <mac address='54:52:00:7d:f8:fc'/> <source bridge='br0'/> <target dev='tkl-joomla'/> </interface> the mac address line controls the guest interface but the host interface seems to get a random MAC address. This is causing a problem for me since I use Cacti to monitor the bandwidth usage of the guest machines. Every time I stop and start a guest, Cacti creates a new interface and I have to reset the graphs to use the new interfaces.
