If you don't need the port-group abstraction (and the switch definition in
libvirt), just create your ovs switch (ovsbr0) with ovs-vsctl and use this
in the VM definition:
<interface type='bridge'>
<source bridge='ovsbr0'/>
<vlan>
<tag id='99'/>
</vlan>
<virtualport type='openvswitch'/>
</interface>
I don't find a lot of documentation about this easier solution. Hope it
helps.
