hi everybody,

how to use this feature? are there any documents about that? i didn't
find it on the website.
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
