What I would probably do would be to run KVM+Libvirt+OVS on the one server in your lab. Define Libvirt networks that are associated with OVS (the Libvirt-OVS integration is fairly well-documented) for the various types of traffic your VMs will need---perhaps you'll need a "management network" and a "data network". For simplicity's sake, I'd probably use different bridges for each network. Then create your VMs and attach them to the appropriate host networks. For example, your "switch VMs" running OVS might have two interfaces: one connected to a management network (over which they'll talk to the controller VM) and one connected to a data network (over which they'll communicate with other switches).
I hope this helps.
