[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#>
Nothing in the openvswitch log file (OVS itself works fine, I can start VMs with the kvm
command line).
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.

There is nothing in this command line to say that the bridge is an
openvswitch bridge, so libvirt is attempting to treat it as the default
Linux host bridge type.
As a matter of fact, as far as I know virt-install hasn't been enhanced
to support direct description of an openvswitch bridge on its commandline.
The best way to solve this problem is to create a libvirt network to
encapsulate the openvswitch bridge, then tell virt-install to use that
network.
1) Put the following xml into a file (e.g. /tmp/ovsnet.xml):
<network>
<name>ovs-br0</name>
<forward mode='bridge'/>
<bridge name='br0'/>
<virtualport type='openvswitch'/>
</network>
2) define and start the network:
# virsh net-define /tmp/ovsnet.xml
# virsh net-start ovs-br0
# virsh net-autostart ovs-br0
3) run virt-install telling it to use the network "ovs-net":
# virt-install --connect qemu:///system --name DSL2 --ram 1024
--vcpus 1 \
--disk path=/tmp/dsl2,size=1,bus=virtio,cache=none \
--network=ovs-br0 \ <======= THIS LINE IS CHANGED.

Thanks Laine, I now have it working. After applying the changes you recommended, I had to
change apparmor settings as libvirt was in enforce mode:
root@qemu-kvm:~/openvswitch# aa-complain /etc/apparmor.d/*
Setting /etc/apparmor.d/sbin.dhclient to complain mode.
Setting /etc/apparmor.d/usr.bin.evince to complain mode.
Setting /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper to complain mode.
Setting /etc/apparmor.d/usr.lib.telepathy to complain mode.
Setting /etc/apparmor.d/usr.sbin.cupsd to complain mode.
Setting /etc/apparmor.d/usr.sbin.libvirtd to complain mode.
Setting /etc/apparmor.d/usr.sbin.rsyslogd to complain mode.
Setting /etc/apparmor.d/usr.sbin.tcpdump to complain mode.
