Here is something you don't see too often.
Here, I have Pear OS 7 which is a Ubuntu based Linux distribution running on my Thinkpad. Pear OS is known for being Cupertino inspired. It is pretty much an OSX themed Linux disto. Inside Pear OS, I have Mountain Lion 10.8.2 running inside a VMware Virtual Guest.
I cloned a few of my old Macs on my Macbook using Fusion 5. The clone VM guest was on a USB drive I had and I was wondering if my VM guests would start up in Linux on a different machine. To my surprise, double clicking the .VMX file, the VM guest launch and ran inside Pear OS running VMware player for Linux. It ran with no problem. I thought there would be some sort of check to prevent this but apparently not.
