So, I'm trying to install Snow Leopard on a virtual machine so I can use the iPhone SDK. The host is my computer running Windows 7 64-bit. However, whenever I try to enable more than one processor, Virtualbox gives me an error message. I've tried Googling it, and it seems no one has the same issue. Obviously, Snow Leopard won't work well with only one logical processor. I considered creating another partition on my computer on which to install OSX, but I only need it for a single program, so I don't think it's really worth it. Anyway, I tried creating another virtual machine to test things, and it turns out that no matter how I have the system configured, trying to enable more than one processor causes VB to crash. Has anyone else used Virtualbox that has found a work-around?
