libvirt users - Oct 2014 - problem with libvirt and ovs bridge

Hello, 
I have created an ovs bridge on which i have attached a port. I would like to
connect my vm to that port,so i have created an xml defining the network.
The xml is: 
<network> 
<name>ovs-snort</name> 
<forward mode='bridge'/> 
<bridge name='snort'/> 
<virtualport type='openvswitch'/> 
</network> 
but when i do virsh net-define /tmp/ovsnetwork.xml i get the error 
error: XML error: unexpected virtualport type -1 
My libvirt version is 1.2.9 
Can you guide me through that?

Hmm, I haven't tested this lately, but here's some old notes on Libvirt
and Open vSwitch:

Sorry, I don't have an immediate test env to try this, maybe you can
examine your debug logs to see if you find more meaningful clues

    log_level = 1
    log_outputs="1:file:/var/tmp/libvirtd.log"

in /etc/libvirt/libvirtd.conf

Restart libvirtd. (And, don't forget to turn it off, once you finish
your debugging - it'll fill your disk space pretty quickly, otherwise.)
