SNL and WPDM on Virtual

I am curious we seem to be having some add problems with SNL and WPDM since installing it on our XEN virtual server from a standalone machine.  Its seem to be connectivity issues as well as license discrepenacies.

Can these products be installed on a virtual machine.  We are using Solidworks 2012 SP5.

All the documentation I have read indicates virtual enviroments are not supported by Solidworks products.....
