tested-by: Wen Ruo Lv<lvroyce at linux.vnet.ibm.com>

tested
1.net-start cmd with bridge mac specified (failed)
2.attach-device cmd with a hot plug nic(ok)

My network is as below:
<network>
<name>default</name>
<uuid>361441af-e1f0-472d-a503-dfcbbefa03fb</uuid>
<forward mode='nat'/>
<bridge name='virbr0' stp='on' delay='0' />
<mac address='00:16:3E:5D:C7:9E'/>
<ip address='192.168.122.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.122.2' end='192.168.122.254' />
</dhcp>
</ip>
</network>

It fails at brSetInterfaceMac-->return ioctl(ctl->fd, SIOCSIFHWADDR, &ifr)
but SIOCGIFHWADDR succeed.
error msg is:
cannot create dummy tap device 'virbr0-nic' to set mac address on bridge 
'virbr0':no such device
