I didn’t pay much attention to VirtualBox when Sun Microsystems first acquired Innotek, but RedMonk’s Michael Coté just posted an interview and demo of the software, and it’s very cool.
In a few clicks, you can see VirtualBox create a Vista instance and run it on the
Mac. There are many options for virtualization at this point, but I would expect Sun to make this its weapon of choice (versus Xen), since it owns it and can tweak it for Solaris.
VirtualBox is a free download available under the General Public License, or GPL.
On the Mac, I’m not sure it’s any better than Parallels, but it is open-source, which should be very appealing for many users.
