[CentOS-virt] bridged kvm guest and ever changing MAC address

[Veiko Kukk]

Hi,

Centos 5.4, dual igb ethernet, kvm guest (Centos 5.4).
br0 is connected to eth0, guest has virtio ethernet connected to br0.
Guest is configured using virt-manager.
When host is booting, br0 gets mac address of eth0.

Every time i start guest (with virt-manager) vnet0 appears and br0 mac 
aadressi on host is changed. Why does it need to change the mac? I'd 
like to keep it same, not to change it every time guest is booting.
