We have been doing this for years with all of our FlexLM/FlexNet license managers.
It works identically on a VM server.
However, be aware that Flexera (the makers of FlexNet) recognize that VM servers can be assigned a MAC address, which can compromise FlexNet.
They implemented an optional tool/method to lock the license to the physical MAC address of the VM host.
This requires installing a daemon directly on the VM host.
At this time, PTC has not implemented this.

In Reply to Mark Steffke:
Can you run Flexnet (or FlexLM ) on a virtual server. Is there confusion over the mac address?
Mac address of the virtual server vs mac address of the hosting hardware- or are they the same?
