I would like to have a psuedo-wire between two guests in KVM. I cannot use a bridge of any type as the guest VMs are actually virtual switches themselves.
Conceptually, it seems that a veth-pair is the way to go, but after much reading I don't see a way to do this. I can put each guest into its own network namespace, and I can link two net-ns together using veth, but I can't get KVM to recognize the interfaces within the namespaces.
Any help is appreciated.
