When using fdisk, 'sudo fdisk /dev/loop0', I had to delete the existing partition. Create a new partition of the same type, 7 for NTFS, but larger. Make the partition active / bootable - I forgot that and had a moment of panic! After mounting the partition, 'sudo kpartx -a windows-xp.img', I used ntfsresize to resize the parition. The commmand looked like 'sudo ntfsresize --size 20G /dev/mapper/loop0p1'. That's it, thanks for the help!

Something along the lines of: sudo virsh define /etc/libvirt/qemu/64bit-Ubuntu-7.10-desktop.xml You might think about using virsh to redefine the specific virtual machine image instead of restarting libvirt and all your virtual machines.
