I'm assuming you purchased a retail copy of Ultimate from your description,
and not an OEM version. You can, under the license terms, migrate your
retail copy as much as you please provided you are only using it on one
system at a time. You will likely need to use the phone activation method on
all activations, but it is perfectly within the usage rights. Running it
under Virtual PC and its emulated hardware is no different than running it
on another machine, and it will require activation within 30 days. This in
no way prevents you from later wiping that system and reloading that same
copy as a normal install to that machine or another.
On the off chance that you purchased a full, generic OEM version you should
be aware that while you can updated the hardware on the system that it was
installed and activated on, you cannot migrate it to another machine. A
virtual machine would likely be considered to be a different system. Once
activated, an OEM license is tied to the machine it was activated on.
