How do I run Mac OS X partition on Windows 7 through a virtual machine?
Here is a quick summary of running OS X on non apple hardware with (and also without) support from virtualization such as VMware. 


Possible - yes
Supported, licensed, intended - no
Legal - you'll need a lawyer to help with that in your specific location.


So, as long as the hardware was Mac you would be probably licensed for Lion and later OS X to run visually no matter what intermediary OS you used as part of the virtualization chain. The how isn't going to be easy since you'll have to defeat either VMWare's checks to prevent any Windows person from running OS X or OS X's checks to ensure it's running on Mac hardware.
