Limitations of running a dedicated server from a virtual machine in Steam?

What are the limitations one will come across when running a dedicated server from with a virtual machine on Steam?

Solution 1:

The wonderful thing about virtual machines is that they are "virtually" identical to real machines. Assuming the host is a powerful enough computer, there should be no problems. However if you run it alongside other virtual machines you may run into the obvious problems such as bandwidth starvation (if multiple machines share one network adapter) or CPU starvation (as they all share one machine's CPU(s)).

There should be no problems that are unique to the fact that it's a virtual machine, though!
