People have been asking for it, Apple has been saying no.  What?  People want to virtualize Apple's Mac OS X operating system - whether on the Mac or on a PC, they simply want to install the OS inside a virtual machine.  Too much to ask for?  Until yesterday, it absolutely was.  So what changed?

A change was made to the Leopard Server End User License Agreement (EULA).  It states:

2. Permitted License Uses and Restrictions.
A. Mac OS X Server Software. This License allows you to install and use one copy of the Mac OS X Server software (the "Mac OS X Server Software") on a single Apple-labeled computer. You may also Install and use other copies of Mac OS X Server Software on the same Apple-labeled computer, provided that you acquire an individual and valid license from Apple for each of these other copies of Mac OS X Server Software.

Sounds like Apple is lifting the ban, but no yet all the way.  You still have to use Apple hardware.  Bummer for PC users.  You still need to buy individual licenses for each virtualized guest OS.  And you can only virtualize the server edition of the OS, not the client version. 

It looks like Apple is making progress, but they aren't fully there yet.  Still, good news for Intel Mac users.
