Thanks, that helped alot. But now i have another issue...

My <interface> section now looks like that:
    <interface type='bridge'>
      <mac address='00:16:3e:04:a0:5f'/>
      <source bridge='br0'/>
      <model type='virtio'/>
    </interface>

I log into win box using virt-manager console and start installing driver 
for network card. And guest hangs. No errors, nothing. Just hangs completely 
during copying driver files. Any ideas?
