[Bridge] MAC address in bridge device

Hi all,
we have a couple of Red Hat 5 servers with OpenVZ with some virtual
machines (VEs). This virtual machines have veths (virtual ethernet
devices), and this devices are attached to a bridge device with main
node ethernet.
# brctl show
vzbr2 8000.001851cfe1c3 no veth130.0
eth0
The bridge device also has an IP because we need to reach host with an
IP in this subnet.
We have noticed a problem:
When we boot the main host, the bridge takes the IP we have defined to
it and the MAC af the eth0 device. That's ok.
But when a veth is joined to the bridge device, this one takes the MAC
of the veth device, so MAC bridge device changes; of course this cause
different kind of network problems because all hosts which were
connected still has the old MAC in its arp table.
We have revised a lot of things, but we don't find any explanation. Does
anybody know a possible cause of this behaviour?
Where can we look to get more information? Is the bridge working as
expected?
Thanks in advance for your help.
Regards.
