I assume that you're referring to a version number.
One of the annoying, nay, irritating, nay, pain in the rectal region issues with the Perspectives client is that it does not easily provide a version number. In Excel, it's File => Help, bang, there's your version number down to the last decimal place. In TM1? Help => About Perspectives, a splash screen giving the oh-so-useful advice that you're on 9.5.2, or 10.1, or 10.2.
The usual way of working out what your release is is to go to the folder that the TM1p.xla file is in, find the tm1p.dll file, right click on it and select properties. You'll see something like 10.2.0.36339 which, given that Iboglix doesn't publish a table which allows us to match this value to the release numbers for versions, fix packs, hot fixes etc, is also not exceptionally useful but if you're on support you can always contact them and get them to advise which version it relates to.

Robin's given you a good answer. I'd add that if the VM is spread over a cluster it adds some failure protection, and also allows the size of the machine that you're running TM1 on to be scaled. The principal downside to a VM in my opinion is that it adds one extra layer to the solution. Extra layers mean more complexity and complexity means, potentially at least, one more layer for issues to hide behind when, as they inevitably do from time to time, "things go wrong". For a smaller installation my preference is still a dedicated physical machine with a backup machine but VMs are, as Robin said, constantly and rapidly improving. (MS putting a great deal of emphasis on "cloudability" in the newer releases of Windows Server being one example.)
