Summary
Virtual machines running OpenSolaris? are unable to connect to other virtual machines over an InternalNetwork?. The issue is seen on a host running OpenSolaris? build 79a.

Details
I have two Virtual Machines - one running OpenSolaris? build 84 another running CentOS 4.4.
I set up NAT and InternalNetwork? on both the VMs.
InternalNetwork? is configured with static IPs. But one VM is unable to reach the other.
Here's what I did.

And here's how the network is configured on the VMs.

I tried this with two VMs running CentOS and it worked fine. I also tried with two VMs running opensolaris and hit the above issue. Issue seems to be specific to OpenSolaris?.
