Is it possible to run mac OS X as guest os, ( with mac os x as host os)? I'ld like to use some virtual testmachines.
I'd like to see it happens too. Parallels can easily become a developer and tester's dream come true.
Not possible for Parallels, VMWare or anyone else who is a company because Apple expressly disallows it. VMWare was asked if this would be a possibility for their upcoming product and they indicated they'd love to do it, and that it would be easy, but unless Apple changed their policy it would not be happening. I suspect the same is true for Parallels. People need to beat on Apple if they want this. I'm sure there will be unofficial hacks based on the ability to install OSX on arbitrary Intel boxes at some point, but that won't be a official/legal solution.
From what I have heard, the current build of OSX_86 does not boot with parallels... I have not tried it myself... just what I've heard.
