I'd like to run a virtualized Ubuntu instance under Mac OS X (10.6). I've used VirtualBox in the past, but am looking for something that will be faster, and don't mind paying for either Parallels Desktop or VMWare Fusion.
Does anyone have experience running Linux guests under either or both programs? I'm primarily interested in doing software development on the Linux guest installation, but I'm also very concerned with the performance and responsiveness the guest OS.
I have a mid-2010 15" MacBook Pro (2.66 GHz i5, 8 GB of RAM, NVIDIDA GeForce GT 330M).
