Probably, the only option for you is to build libvirt from source, unless
you are ok with using Fedora 17 Alpha (I believe this is the only
mainstream distro that has the bleeding libvirt version, but I could be
wrong on this). It should not matter what kind of OVS version you are
using. The only restriction is that ovs-vsctl utility (from Open vSwitch)
must be in the $PATH, because libvirt needs to call it.

Currently only bridged networks are supported, so you must create the OVS
bridge beforehand:

> ovs-vsctl add-br ovsbr
>

 The other thing you need to do is edit the Domain XML file:

> <interface type='*bridge*'>
> <mac address='52:54:00:d0:3f:f2'/>
> <source *bridge*='*ovsbr*'/>
> *<virtualport type='openvswitch'>
> </virtualport> *

<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
> </interface>
>
And then (re)start the VM.

To verify, if libvirt attached VM interface to the ovsbr as expected, you
should run the following command and look for vnetX interface:

> ovs-vsctl show
>

Hope this helps.
