I use VirtualBox OSE for virtualizing test environments for Miro development. I built a Windows XP vm a year ago and when I did it, I put it on a virtual disk that was 8 GB which turned out to be waaaay too small for my needs. It's non-trivial to build a Windows build environment for Miro so I really wanted to clone the partition to a new virtual disk that was a lot bigger, then resize the partition rather than create a new virtual disk and reinstall and set everything back up.

I pretty much did that this morning in a couple of hours.

First thing I did was download the LiveCD of Clonezilla (version 1.2.1-23) and the LiveCD of GParted (version 0.4.1-2).

Second thing I did was create a 25 GB virtual disk in VirtualBox.

Then I attached the new virtual disk to the winxp vm that I had. Thus it should show up as hdb.

I booted into the Clonezilla LiveCD, cloned the old virtual disk to the new one keeping the partition sizes the same and making sure to copy over the MBR, too.

I switched around the virtual disks attached to my winxp vm and booted into the new virtual disk--worked great!

I booted into the GParted LiveCD, launched qtparted and grew the NTFS partition so that it used the whole virtual disk.

Then I booted into the new virtual disk. It did an NTFS disk check on startup which I thought might indicate the process didn't work right. Disk check passed, Windows XP booted and everything worked as well as I expected it to.
