Hi.
(sorry I replyed in last email rather than posting to the list..)
Thanks - after issuing the commands it has correctly resized.. So it is
possible to resize (with the extra steps..)
Here is the output from the ntfsresize command:-

Welcome to virt-rescue, the libguestfs rescue shell.

You have to mount the guest's partitions under /sysroot
before you can examine them.

I managed to track this down to some type of difference in the
ntfsresize utility in Ubuntu 11.10 vs Fedora 16, even though they are
almost the same version of the same program.
Attached is a test script that fails on Ubuntu 11.10, but works fine
on Fedora 16. The failure on Ubuntu 11.10 is exactly the same as the
one you described.
Fails with: ntfsresize v2011.4.12AR.4 (libntfs-3g) [Ubuntu 11.10]
OK with: ntfsresize v2011.4.12 (libntfs-3g) [Fedora 16]
Fedora is carrying about half a dozen patches to ntfs-3g. It's not
clear that there is a "smoking gun" amongst them, but until proven
otherwise I'm going to put this down to a bug in the Ubuntu package.
It's certainly worth investigating if someone has more spare time.
