RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jinxin Zheng 2011-03-31 08:44:48 UTC
Description of problem:
inspect-list-applications cannot detect applications installed in x64-based Windows image, whereas it works for 32 bit Win.

Taking the xenpv driver as an example, I installed xenpv on a 32 bit Windows 2003 image from inside the guest, and guestfish successfully could detect it:

...
[2] = {
  app_name: Red Hat Paravirtualized Xen Drivers for Windows(R)
  app_display_name: Red Hat Paravirtualized Xen Drivers for Windows(R) 1.3.4-1
  app_epoch: 0
  app_version: 1.3.4-1
  app_release:
  app_install_path:
  app_trans_path:
  app_publisher: Red Hat, Inc.
  app_url: http://www.redhat.com
  app_source_package:
  app_summary:
  app_description:
}

But when we come to the 64 bit Windows, we get nothing from the output.

Version-Release number of selected component (if applicable):
libguestfs-1.7.17-16.el6

How reproducible:
Always

Steps to Reproduce:
1.
Setup a x64-based Windows image. Boot into the guest using KVM or Xen, and install some applications like xenpv driver.

2.
Quit the guest and use guestfish to detect the installed application.

guestfish -a windows-64bit.img
...
><fs> inspect-os 
/dev/vda1
><fs> inspect-get-mountpoints /dev/vda1
/: /dev/vda1
><fs> mount /dev/vda1 /
><fs> inspect-list-applications /dev/vda1 
><fs> 

  
Actual results:
No output.

Expected results:
Descriptions of installed applications.

Additional info:
I think you need to look for some registry key other than HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for the 64 bit Windows.

Comment 1 Jinxin Zheng 2011-03-31 08:56:47 UTC
OH, I think the xenpv driver is a 32-bit program that run in WOW64 mode. It should be found in HKEY_LOCAL_MACHINE\Software\WOW6432node.

I did not try the native 64-bit program case, which I'll later have a test.

Comment 2 Richard W.M. Jones 2011-03-31 09:01:19 UTC
Could you attach the HKLM\SOFTWARE hive from this
windows guest to the bug?

Do:

$ guestfish --ro -a windows-64bit.img -i \
  download win:/windows/system32/config/software software
$ file software 
software: MS Windows registry file, NT/2000 or above

Those commands should produce a binary file called 'software' in
the current directory which you can just attach.

Compressed hive file of the Windows image

I compressed the hive file. It's from a Windows 7 x64 image.

Well, I tried the 7zip 64bit version, and it was correct.

><fs> inspect-list-applications /dev/vda1
[0] = {
  app_name: {23170F69-40C1-2702-0920-000001000000}
  app_display_name: 7-Zip 9.20 (x64 edition)
  app_epoch: 0
  app_version: 9.20.00.0
  app_release: 
  app_install_path: 
  app_trans_path: 
  app_publisher: Igor Pavlov
  app_url: http://www.7-zip.org/
  app_source_package: 
  app_summary: 
  app_description: 
}

Then it's a 32bit-on-64bit issue.

The hive file on which I performed the test with 64 bit 7-zip.

Comment 8 Jinxin Zheng 2011-08-18 06:56:46 UTC
Reproduced on libguestfs-1.7.17-19 using:

$ guestfish -a windows-64.img <<EOF
inspect-os
mount /dev/vda1 /
inspect-list-applications /dev/vda1
EOF

The windows-64.img has xenpv-win driver installed.
There's no output running the script.

Verified with libguestfs-1.7.17-26. We get:

[0] = {
  app_name: Red Hat Paravirtualized Xen Drivers for Windows(R)
  app_display_name: Red Hat Paravirtualized Xen Drivers for Windows(R) 1.3.4
