With Virtual PC 2004 each VM sees the host network
card independently, but the VM does not see the host
PC OS.
The trick of the software is to create a virtual hw
world for each VM to use. You will notice the mac
address is different inside each host for a single
nic.
The network connections in each VM have their own ip
address and mac address, logically and physically,
just like you would have with separate PCs.
Here is some info from the host pc and a couple vm's
if its not too big to post:
