Resizing a KVM Windows virtual disk image
Just noticed the incoming link from Bryan Murdock on how he went through the process of resizing a Windows virtual image in a qcow2 file format to add more disk space on the virtual image. I haven’t actually done this myself, but it looks like there are issues resizing an image that has an NTFS filesystem. If you need to resize your image, check out Bryan’s post on how he did it here. (I like his method better than others)
I also found a good wiki page (I think it’s new) showing the guest OS’s that work (or don’t work) with KVM.

This is even easier for an NTFS XP image…
dd if=/dev/zero of=some_file bs=1024 count=10240000
cat some_file >> existing_xp_image
Restart the KVM machine and extend the partition with Partition Magic.
