Perhaps you should take a look at a few of these articles:
http://en.wikipedia.org/wiki/Virtualization
http://en.wikipedia.org/wiki/Hypervisor
http://en.wikipedia.org/wiki/Full_virtualization
http://en.wikipedia.org/wiki/Paravirtualization

 As was suggested, you can run a full virtualization hypervisor, i.e.
VirtualBox, which is basically a layer of software that acts like hardware
with or without a CPU that has Intel VT-x or AMD-V CPU virtualization
extensions.


I don't care, but I believe, that if you run windows under virtualbox, then

MS licensing doesn't work that way. Typically, if you own a copy of the
software, you are free to run it in a virtual machine. You can read the EULA
yourself and find the terms. See the following website to find the EULA for
any MS product:
http://www.microsoft.com/About/Legal/EN/US/IntellectualProperty/UseTerms/Default.aspx

This happens to be the terms for Windows 7 Home Premium edition, which makes
it very clear that you can run the software virtualized inside of
VirtualBox.

d. Use with Virtualization Technologies. Instead of using the software
directly on the licensed computer, you may install and use the software
within only one virtual (or otherwise emulated) hardware system on the
licensed computer. When used in a virtualized environment, content protected
by digital rights management technology, BitLocker or any full volume disk
drive encryption technology may not be as secure as protected content not in
a virtualized environment. You should comply with all domestic and
international laws that apply to such protected content

You can run a hypervisor inside of a hypervisor. You won't get the same
performance on your PC as running VM on a multi-million dollar mainframe,
but it is still pretty cool feat.
