Last time I try virtualization on my desktop OS was using Virtual PC 2007 from microsoft. I was pretty satisfied with its working and it does a good job for me. However, today I was trying to using that on my Vista Home Premium edition and found that Microsoft doesn’t support that, and when I ignore that warning and try to use. I end up messing my CentOS 5 installation and Fedora 8 installation.

But then I found VirtualBox  (http://www.virtualbox.org/) It is way better and mature then Microsoft’s Virtual PC 2007. It is free as well. I run Centos5 on my Vista Home Premium successfully. I observe that it is slight faster than Virtual PC 2007 as well. I must say I love virtualBox more than that. And will use VirtualBox only. However, it seems it consume more resources on host OS then VirtualPC, but atleast it runs the software I wish to run.

Good work Sun, this time you beat Microsoft :).
