Check that they're using your static bridge. 'virsh dumpxml <vm>' will
have a section like:
<source network='bcn_bridge1' bridge='bcn_bridge1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x05'
That tells you that the interface is MAC '52:54:00:71:20:fa' is "plugged
in" to the bridge 'bcn_bridge1'. If that doesn't connect to the right
bridge, then you need to change it (virt-manager has a simple to use GUI
for this, or you can use 'virsh edit <vm>' if you're comfortable editing
