What's the status on this? I've been wanting this for some time now too
and the comments left here are not very clear as to what the actual
stumbling block is for why this isn't fixed yet.

Connecting n VMs together without connecting them to the host and without being root is possible in only two ways at the moment:
- Using UDP MC sockets which are terribly inefficient (A file transfer between two VMs through ssh managed to load my machine up to 2% CPU. The same transfer via the user network between VM and host loads it up to about 50% as it should (4 cores))
- Using VDE which currently requires me to recompile qemu/kvm.

Can anybody from the server team or whoever knows about these processes
comment on what it would take to get this progressed?
