VirtualBox

Recently, I start to play virtualization with my new toy, Intel Q9450 box. While searching information from the net, I found VirtualBox.

Wow! It really an ultra light-weight virtualization software. I start to install some guest OS. FreeBSD, Centos and Ubuntu. Some experience I want to share:

1. It seems that VirtualBox(1.6.2) doesn't support 64bits guest OS. Even my VirtualBox is 64bits.
2. Adding lan bridge to your guest OS require manually group your lan interface to bridge.
3. Cloning guest OS require VirtualBox's cloning command line tool:

VBoxManage clonevdi centos5.2.vdi centos5.2-2.vid

This command is okay if you save your Virtual Disk File in default location (C:\Documents and Settings\yourid\.VirtualBox\VDI).

If you have save your virtual disk file in another place, you have to specify the full path (both input file name and output file name). E.g.

VBoxManage clonevdi d:\vbox\centos5.2.vdi d:\vbox\centos5.2-2.vid

Otherwise you will got an error saying that Could not access hard disk image.
