It looks like you are using vconfig to configure a VLAN on eth0 as eth0.2000,
and then adding both eth0 and eth0.2000 to your bridge. I don't think that is
going to work. I think that you will instead have to create your VLAN as a
port on the bridge, e.g.:
ovs-vsctl add-port br0 br0.2000 tag=2000 -- set interface br0.2000
type=internal
See the examples in ovs-vsctl(8) for more information.
