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.

Doc Type: Bug Fix
Doc Text:
Cause: Windows guest has an HP recovery partition. Consequence: libguestfs confuses the HP recovery partition with an ordinary Windows partition, so thinks the guest is dual-boot. Various virt tools including virt-v2v and virt-p2v refuse to deal with multi-boot guests, so they wouldn't work. Fix: libguestfs now recognizes the special HP recovery partition. Result: libguestfs, virt tools, virt-v2v, and virt-p2v can now be used on these guests.

Description Richard W.M. Jones 2011-08-08 16:44:54 UTC 
+++ This bug was initially created as a clone of Bug #729075 +++

Description of problem:

This error occurred during a routine virt-p2v conversion:

Aug  8 11:10:16 virtp2v-server kernel: [ 9943.068103] CE: hpet increased min_delta_ns to 7500 nsec

Version-Release number of selected component (if applicable):

libguestfs 1.8.9

The systemroot directory is c:\WINDOWS
Comment 1 Richard W.M. Jones 2011-08-08 17:01:54 UTC 
The root cause appears to be because the system has an
HP_recovery partition (as drive D:)  This contains files
with names like autoexec.bat and boot.ini which confuses
our windows root detection.

Comment 13 Yuyu Zhou 2012-05-09 02:21:31 UTC 
Reproduced accord to comment 12 on libguestfs-1.7.17-26, verified on libguestfs-1.16.19-1.

Steps:
1. Make sure libguestfs-winsupport is installed.
2. Take any Windows guest.
3. Create a second disk (called 'test1.img') using these commands:
cd /tmp
guestfish -N fs:ntfs -m /dev/sda1 touch /AUTOEXEC.BAT
4. Try to inspect the guest + the second disk:
guestfish --ro -i -a /home/data/images/Win2008r2-64-hvm.raw -a /tmp/test1.img

Test result:
On  libguestfs-1.7.17-26:
At step 4, following error message shows up.
libguestfs: error: cannot resolve Windows %SYSTEMROOT%

On libguestfs-1.16.19-1:
At step4, Windows guest is found and mounted correctly as following:

# guestfish --ro -i -a /home/data/images/Win2008r2-64-hvm.raw -a /tmp/test1.img

Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.

Type: 'help' for help on commands
      'man' to read the manual
      'quit' to quit the shell

Operating system: Windows Server 2008 R2 Standard

According to above result, change this bug to VERIFIED.
