1836094 – virt-inspector fails to display the applications of RHEL 9 and OpenSUSE Tumbleweed (using sqlite rpmdb)

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.

Comment 1 Richard W.M. Jones 2020-05-15 12:14:14 UTC

It's likely this applies to Fedora Rawhide guests as well.  Both
now use a different RPM database (sqlite for Rawhide, not sure about SUSE)
so we need to use librpm in order to process the database instead
of assuming they're all using BDB.

Comment 3 Eric Hadley 2021-09-08 16:42:18 UTC

Bulk update: Move RHEL-AV bugs to RHEL9. If necessary to resolve in RHEL8, then clone to the current RHEL8 release.

Comment 4 YongkuiGuo 2021-09-09 02:19:31 UTC

I retested this issue and it was fixed on RHEL9. See this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1935181. Due to this issue, on RHEL8 virt-inspector also fails to detect the rhel-guest-image-9.0-xxx.qcow2. (I see we don't support handling RHEL n+1 image on RHEL n officially)

On rhel8.6 bare metal:
# virt-inspector -a rhel-guest-image-9.0-20210906.7.x86_64.qcow2
libguestfs: error: filesize: /var/lib/rpm/Name: No such file or directory

If there is a plan to fix this issue on RHEL8, maybe we should revert this bug to RHEL8 again. Otherwise, we can close it.

Comment 5 Richard W.M. Jones 2021-09-09 07:18:57 UTC

Let's move this back to RHEL 8.  It should be possible to
backport this fix.

Comment 6 YongkuiGuo 2021-09-09 07:51:43 UTC

Okay, thanks.

RHEL 9.0 guest compose: http://download-node-02.eng.bos.redhat.com/rhel-9/composes/RHEL-9/RHEL-9.0.0-20210924.5

libvirt need to test RHEL 9.0 PPC guest installation on a RHEL 8.5 PPC host . 
The command we use to verify the installed guest is working normally. But it failed while I can start the guest using this image and log on and operate normally within the guest.

# virt-sysprep -a /var/lib/libvirt/images/image-builder3.qcow2 --run-command 'echo > /etc/machine-id'
 [   0.0] Examining the guest ...
virt-sysprep: error: no operating systems were found in the guest image 
If reporting bugs, run virt-sysprep with debugging enabled and include the 
complete output:

  virt-sysprep -v -x [...]

Comment 8 Richard W.M. Jones 2021-09-27 07:17:50 UTC

Can you add -v -x options to find out what the real problem is.

However one issue is going to be that examining RHEL > n guest using RHEL = n
host is not supported.
