NFS supports both TCP and UDP connections, but the NFS server has to have indicated its willingness to use TCP. If it doesn't do that, then the client will use UDP. If you can ping the mount server from the guest, then IP connectivity is present and the problem is not in the wires, virtual or otherwise. There could be firewall interference. Check the NFS server to see if it has a TCP listen up on port 2049. Do the console logs of previous logons of the same server show the same message? I.e. is the really a new problem?
