Hello, When I install Microsoft Virtual PC 2007 via Parallels Desktop, it won't let me run it. It says: "Virtual PC is incompatible with the physical processor in this computer. Virtual PC requires at least a Pentium II ( or equivalent ) processor. I am on a MacPro running Mac OSX 10.5.6. 2 GB of RAM and 1TB hard drive with lots of free space. I am running Vista Ultimate with my Parallels Desktop 4.0. My MacPro has a 2 x 2.8 GHz Quad-Core Intel Xeon processor. So I know it has more power than a Pentium II. How do I fix this so that I can run Microsoft Virtual PC on my Mac Pro? Thanks!
Are you trying to run a VM inside a VM? . I doubt highly that would work. If it did, it probably wouldn't work well. Virtual PC not an Operating System, but a Virtualization Product.
I am basically treating Windows Vista with Parallels the way I would treat Windows Vista on a PC machine.
You cannot run Microsoft Virtual PC on your Mac Pro. What you try to do is to run Virtual PC on your Vista which runs inside a VM hosted on your Mac Pro. That won't probably work, just as trying to run Virtual PC in a virtual machine created by Virtual PC on a real PC wouldn't work either. Now, if you boot your Mac natively in Windows Vista (BootCamp), then you CAN install and run Virtual PC on it.
Virtual PC requires hipervisor, which is already intercepted by virtualization processor, If you want to run virtualization software try Virtuozzo http://www.parallels.com/products/virtuozzo/ Note, you need to uninstall Parallels Tools
