The `ntfsresize' tool is broken somehow, or it is possible that the
underlying first partition on the disk is broken.  Unfortunately the
error message got truncated somehow.

To find out more, set the following environment variable before
running virt-resize:

  export LIBGUESTFS_DEBUG=1

This will display the complete output from ntfsresize, to stdout &
stderr, and should hopefully give you more information.

Another thing you can try is:

  virt-rescue --ro -a vm-2000-disk-1.qcow2.out
  ><fs> ntfsresize --check /dev/sda1
