It's a very new feature, only in libvirt-0.9.10 and newer. Here is the
commit log that describes additions to the XML to configure an interface
to use an openvswitch bridge:

    network: support Open vSwitch
   
    This patch allows libvirt to add interfaces to already
    existing Open vSwitch bridges. The following syntax in
    domain XML file can be used:
   
        <interface type='bridge'>
          <source bridge='ovsbr'/>
          <virtualport type='openvswitch'>
            <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'/>
          </virtualport>
        </interface>
   
    or if libvirt should auto-generate the interfaceid use
    following syntax:
   
        <interface type='bridge'>
          <source bridge='ovsbr'/>
          <virtualport type='openvswitch'>
          </virtualport>
        </interface>
   
    It is also possible to pass an optional profileid. To do that
    use following syntax:
   
       <interface type='bridge'>
         <source bridge='ovsbr'/>
         <virtualport type='openvswitch'>
           <parameters interfaceid='921a80cd-e6de-5a2e-db9c-ab27f15a6e1d'
                       profileid='test-profile'/>
         </virtualport>
       </interface>
   
    To create Open vSwitch bridge install Open vSwitch and
    run the following command:
   
        ovs-vsctl add-br ovsbr
