The results will be highly dependent on how is networking configured on your VMs. If they are set up so that they behave as just a bunch of computers on the same network with their own IP addresses from the same network address space, then all should just work. However often the basic/default setup is such that the VM isn't directly visible to other VMs on the same host or from other hosts on the network. There might be some port forwarding involved etc. Opentalk can accommodate most of these situations, but will require specific setup. You'll need VW 7.5 or latest. Look up the section on 'Network Configuration' in Chapter 5 (Broker Configuration) in OpentalkDevGuide (or see the Opentalk release notes for VW7.5). That should give you enough information to get going. If not you'll have to provide more details about the networking setup of your VMs to get more specific advice.
