It is possible, and in some situations preferable* to run virtual platforms in a virtual layer.

I use a combination of Virtual PC and VMware Server to host my virtual instances, but I find that running these applications slows down my machine during boot up and log on.

It is important to remember that SVS layers are still subject to Group Policies, even though the layer may be activated after the application of the policies.

A local cache of the Group Policies are held on the local machine when a member of an Active Directory and remain in force for the duration of the refresh interval.

If you need to create a printer as part of an SVS Layer, you need to restart the Print Spooler service after the layer is activated.
