I think you can do something like this:
ovs-vsctl \
-- add-br br0 \
-- add-port br0 bond0 tag=0 \
-- add-port br0 bond0.11 tag=11 \
-- add-port br0 bond0.12 tag=12 \
-- add-port br0 vm1 tag=0 \
-- add-port br0 vm2 tag=11 \
-- add-port br0 vm3 tag=12
I wouldn't leave anything without a tag, that would make it a trunk
port.
If you didn't break out the child interfaces from bond0 then it could be
simpler:
ovs-vsctl \
-- add-br br0 \
-- add-port br0 bond0 \
-- add-port br0 vm1 tag=0 \
-- add-port br0 vm2 tag=11 \
-- add-port br0 vm3 tag=12
