Dear all, hi!

I am a new user to ovs. I am now having a project which needs to construct
virtual network topology. I want to use ovs but I don't know if the
following requirements can be satisfied.

I want to construct a topology with four ovs, namely o1, o2, o3 and o4. The
connection is o1-o3, o1-o4, o2-o3, o2-o4. For o1 and o2, I want to bind
each of them to two real NIC (while in the cookbook, we bind only one NIC),
through which each ovs can connect to two real switches outside. For o3 and
o4, I don't want to bind them to any real NIC, but the VMs will connect to
them. Actually, this is a three-level network, in which the low level ovs
(o3, o4) connect to VMs, which the mid level ovs (o1, o2) connects to two
high level real switches. The VMs can be inter-connected.

I don't know if it is possible to do that? Thanks for your kindly help!
