[libvirt-users] Libvirt 1.0.5 with Openvswitch 1.11.90: unable to add bridge br0 port vnet0 operation not supported

Howdy, Running the most recent OVS and libvirt I'm running into the following error message with virt-install: root@qemu-kvm:~/libvirt-1.0.5#<mailto:root@qemu-kvm:~/libvirt-1.0.5#> ovs-vsctl -V ovs-vsctl (Open vSwitch) 1.11.90 Compiled May 6 2013 22:37:22 root@qemu-kvm:~/libvirt-1.0.5#<mailto:root@qemu-kvm:~/libvirt-1.0.5#> root@qemu-kvm:~/libvirt-1.0.5#<mailto:root@qemu-kvm:~/libvirt-1.0.5#> virt-install --connect qemu:///system --name DSL2 --ram 1024 --vcpus 1 --disk path=/tmp/dsl2,size=1,bus=virtio,cache=none --network=bridge:br0 --vnc --os-type=linux --cdrom /dev/sr0 Starting install...

Any clues? I'm not too sure how to trace libvirt calls to OVS (according to the release notes, versions 1.0+ of libvirtd should work with OVS. Note: I am not using brcompat, I believe it's obsolete in the OVS version I'm running). Thanks, Chris.
