Hey all,
I resized a partition inside a KVM RAW file system disk image. When I
start the Win7 virtual machine it does not report the new partition
size. It shows the file system as 15GB instead of the 50GB size of the
partition that it lives on. I gather from hours so reading the manual
that I need to increase the NTFS file system size to fill the new larger
partition where it lives.
The ntfresize command does not seem to be compatible with disk image
files. Do I have to mount the disk image file with a loopback first?
I tried doing it inside the Win7 VM using the disk management tools but
that didn't work either.
Any suggestions welcome.

Do I have to mount the disk image file with a loopback first?It's generally recommended to use Windows tools to do NTFS re-sizing. I can't help with that, but from Linux you would need to run kpartx -a -v /path/to/image/file to create the /dev/mapper/loop?p? devices for the partitions within the image. You can then access those devices just like regular disk partitions. Run "kpartx -d -v /path/to/image/file" to delete the loop devices. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.

I would recommend http://gparted.org/livecd.php over the microsoft-supplied tools, in a heartbeat. Boot off that Live image on a CD or thumbdrive (or use the version of GPartEd included with the System Rescue Live CD from http://www.sysresccd.org/ ), select the correct disk from the drop down menu in the upper-right, set the borders of the partitions where you want them with the GUI, then tell it to Apply the pending actions. If I recall correctly, the disk management tool in the windows MMC won't resize the partition it's running from, by the way.
