Hi,
(I am assuming that the VMs are meant to be hosts, and the OVS are running
on the system and not in the VMs)
You can probably use virtual interfaces. the following command creates a
pair of Virtual interfaces on the system;
sudo ip link add type veth
sudo ifconfig veth0 up
sudo ifconfig veth1 up
the pair created will be named veth0 and veth1. Running it the second time
will create veth2 and veth3 and so on. (restarting the system will delete
these interfaces.)
The specialty of these virtual ports is that the pair created is liked,
that is a packet sent on veth0 will come out of veth1. so you can create 2
of these pairs, and add them like regular ports in the ovs1, ovs2 and ovs3
like this;
controller 1 controller 2 controller 3

VM_1 VM_2 VM_3
Tell me if it works!
