From a data plane perspective, you can connect them in the same way you
would go about connecting multiple physical switches together. For
example, you could use an interface from your VM (say, eth1) and connect
that to the OVS bridge running in the VM. That interface is then
connected to your hypervisor's switching functionality, which in turn
connects it to the physical network. All three OVS bridges are now part
of the same L2 broadcast domain.

From a control plane perspective, you'd (typically) need to use an
OpenFlow controller if you wanted them to act as a single (logical)
switch consisting of multiple (virtual) switches.

I hope this helps.
