Perhaps someday Apple will work to allow Mac OS X Server virtualization on its own hardware...

Of course you realize that Mach already incorporates virtualization from the kernel, right?

...and we can effectively use that to run multiple instances of Mac OS X Server, a la traditional VMs, Solaris zones, or LPARs how?


It doesn't really matter what Mach is capable of if such functionality doesn't translate to a supported, high-level featureset in the product.


Hey, it's further along than the non-products that aren't being offered commercially ;)


The support for hosting OSen is already there and being used today in every copy of OS X you run. It's just that OS X only launches one OS on top of Mach. It *could* launch more instances.

The VMM code is in the PPC section of xnu it would seem...

The bluebox related system calls that Google found me don't appear to be in the current code though. I'm no kernel engineer though so I won't speculate on how any of this could be used. That is a question for the macosforge.org people.
