Heya Laine,
Here's some quick notes to associate libvirt guests to Open vSwitch.
Configure Open vSwitch ----------------------
Now that a regular Linux bridge is configured, let's try to configure an OVS brdige and get IP addresses from that space:
Create an Open vSwitch bridge device called 'ovsbr', and display the current state of OpenvSwitch database contents:
$ ovs-vsctl add-br ovsbr $ ovs-vsctl show
Add a virtual ethernet interface called 'veth0' with
$ ip link add name veth0 \ type veth peer name veth1
Add 'veth0' ethernet device to the Linux bridge 'br0', and enumerate all bridge devices:
$ brctl addif br0 veth0 $ brctl show
I don't really see why you are linking ovs to a traditional software bridge. You now have the overheads of both bridging & ovs code in your data path. Surely it is better to connect ovs with your physical NIC, taking traditional bridges out of the loop completely.
