Currently, the only thing limiting OSX Server running virtualized on generic hardware is Apple’s insistance that it only run on Apple hardware. VMWare, VirtualBox and Parallels have complied and made it impossible for OSX to run on anything but Xserves and Mac Pros.
Apple has allowed the virtualization of OSX on Apple’s own hardware since a change of EULA in Leopard.
But perhaps Apple is loosening its hold on the OSX Server? An interesting tidbit from Virtualization.info shows there is some code which could indicate that Apple OSX Server might be made to run as a VM on its vSphere Cloud infrastructure software.
vSphere is going to support Mac OSX, by providing EFI Support and support for Darwin as guest OS.
vSphere doesn’t run on Apple hardware so it is interesting that VMware is building in support for Apple’s OS. A generic virtualization solution would go a long way into fixing the hole left by Apple’s exit of the Xserve market and would show that Apple has its finger on the pulse of the direction of virtual computing.

vSphere to support Mac OSX?

There were some text that listed the various types of host, including Mac OSX.

As you can see, there is mention of EFI support which is required to boot Mac OSX. Does this mean future version of vSphere will support virtualizing Mac OSX?
New guestOS types?

There was a section that I came across which listed all supported guestOS types, here you can see there have been a few more that were added between vSphere 4.0 and 4.1. One interesting thing that I am not sure if a lot of people have noticed, is theVirtualMachineGuestOsIdentifier in the vSphere API. This basically provides the guestos identifier that is supported in each release of VI/vSphere. Interesting enough, a darwin guestos support has been documented as of vSphere 4.0:
