Description Richard W.M. Jones 2012-02-27 18:07:43 UTC

+++ This bug was initially created as a clone of Bug #797760 +++

This bug happens both upstream (1.17.8) and in RHEL 6.3 (1.16.x)
and it seems likely that it has always been broken in virt-resize.

Description of the bug by Grant Williamson:

1 - Grab the sysprep tools from
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=11282

2 - Create a sysprep.inf file.

3 - Sysprep the WINDOWS XP SP3 Image
Copy the sysprep.inf to where you extracted sysprep.exe
i.e. c:\sysprep
then from this directory run.
sysprep -reseal -mini
wait till guest switches off.

4 - Resize the XP image.
truncate -s 40G NEW.raw
virt-resize --expand /dev/sda1 OLD.raw NEW.raw

5 - Boot image, chkdsk runs.
  - Machine reboots.
  - sysprep runs
  - machine reboots
  - boot hangs with BSOD message
  - shutdown/restart, same BSOD message.

6 - Workaround fix.
  - Shutdown guest
  - losetup /dev/loop0 NEW.raw
  - kpartx -a /dev/loop0
  - ntfsfix /dev/loop0
  - kpartx -d /dev/loop0
  - losetup -d /dev/loop0


Resizing on an NON SYSPREP image works.

I can reproduce this.

However I cannot fix it.

I added an ntfsfix binding:

https://www.redhat.com/archives/libguestfs/2012-February/msg00109.html

I tried modifying virt-resize so that it calls ntfsfix after
resizing ntfs partitions.  However that did not fix the problem.

I also tried running ntfsfix after seeing the UNMOUNTABLE_BOOT_VOLUME
error, however that just made the guest hang during boot.

Comment 1 Richard W.M. Jones 2012-02-27 19:36:42 UTC

Removing
ExtendOemPartition=1
fixes the problem.  I will document it in the virt-resize
man page.

Comment 2 Richard W.M. Jones 2012-02-27 20:03:39 UTC

Fixed (by documentation) upstream in 1.17.9:
