   Hi:
   I have two HVM domU ubuntu 10.04 Lts and Window XP running. I have
   assigned PCIe device to each of this domU. I would like to
   communicate these two VM. Can anyone give me some idea on how to do.
   I did some research on IVC but unable to get answer. Anything will
   be appreciated.

Simply setup an extra interface on each VM, on the same IP subnet and
they'll communicate to each other :)
i.e. something like:
ifconfig eth0:0 192.168.2.1
and then on the other VM
ifconfig eth0:0 192.168.2.2

This works, but it shares the network traffic with the same network as the existing traffic. This is possibly a security issue if the existing network is not fully trusted.

If the 2 VM's are on the same Hypervisor, and they're using a IP subnet which other hosts don't use then it doesn't get "shared".

Use VLAN if you need security :)
