I didn't ask my question very well. I have fake bridges already.

# ovs-vsctl show
c6def17d-2cc6-499e-a461-af4fe9aab78a
    Bridge public
        Port "em1"
            Interface "em1"
        Port "veth0_one"
            Interface "veth0_one"
        Port public
            Interface public
                type: internal
    Bridge storage
        Port "veth2_one"
            Interface "veth2_one"
        Port storage
            Interface storage
                type: internal
        Port "vlan20"
            tag: 20
            Interface "vlan20"
                type: internal
    Bridge management
        Port "veth1_one"
            Interface "veth1_one"
        Port management
            Interface management
                type: internal
        Port "vlan10"
            tag: 10
            Interface "vlan10"
                type: internal
    ovs_version: "2.1.0"

I need to connect dom0 to vlan10 and vlan20. I need to be able to connect
from the virtual hosts to the dom0 through openvswitch. I want to use
resources on the host, from OpenNebula running in a virtual host. I can't
access the host, except on the public interface over the public network. I
want to preserve the public interface for public traffic. I want to
connect to dom0 through the vlans. Can I configure a virtual interface to
openvswitch in dom0 ?

Thanks for taking time to answer my questions.
