linked to the physical LAN, you are in business. All vms can see each other
and also see all machines on the LAN.

If the vms are on a local virtual network there is no way that they will
see a vm on another host, even if the hosts are on the same LAN. You would
need to route traffic between the two virtual networks across the physical
network. It is certainly possible but not easy.

I have done it to emulate routing between two sites and it works, but it
requires a router (ie a virtual machine configured as a router) on each
host.

Thanks Bill,

I will appreciate if you can provide some more details on how to configure a
virtual server as a router.

Thanks,
Moe

Exactly the same way as you would configure a physical machine as a
router. I use Server 2003 RRAS, but for a simple router like this you could
use NT or XP workstation or a Linux workstation if you are familiar with
that OS.

You configure the vm with two NICs, one connected to the physical
network and one connected to the virtual network. You enable IP routing and
add static routes (or set the default route) to send the traffic for the
other site to the other router through the LAN. eg

If you are really pushed for memory, you could put your virtual machines
in a virtual network linked to a loopback adapter on the host and let the
host do the routing. I prefer to keep the host out of the picture.
