I installed the GPL Open Source virtualization app VirtualBox tonight with Windows 7 so I could run the BlackBerry simulator on my Mac. It runs basically everything you would need:

Presently, VirtualBox runs on Windows, Linux, Macintosh and OpenSolaris hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7), DOS/Windows 3.x, Linux (2.4 and 2.6), Solaris and OpenSolaris, and OpenBSD

Been running it for a bit, and so far so good, and really impressed by how easy it was to setup. Score one more for Open Source 🙂

VirtualBox even has some well made screencasts to get you started. I’ve included one below:

Vodpod videos no longer available.
