Hi
It's worth mentioning that unless (like me) you need a particular feature provided by VMware and not by virtualbox you might want to consider using that instead.
We use VMWare at work and I'm quite keen to stick with it. I'm hoping to convince work to switch to Linux for development and deployment, but each developer still needs to run their own MS SQL server.....
Fair enough, as much as VMware annoys me sometimes I am stuck with it due to a dependency I have with the p2v tools, also none of the OSS alternatives I have tried have come anywhere close to ESX(i) in terms of performance when running a good number of VM's on the same host and the management tools available.
Although I'm rapidly going off it. It seems incredibly slow and unstable compared to the when it's running on Windows.
I'll take a look at virtualbox. What's KVM like?
