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.

Try to detect Rocky linux with virt-inspector:

1. Download Rocky linux iso and install it
# wget https://download.rockylinux.org/pub/rocky/8/isos/x86_64/Rocky-8.5-x86_64-minimal.iso

2.
# virt-inspector -a /var/lib/libvirt/images/Rocky-8.5.qcow2

The distro and osinfo are not correct.

The patch didn't compile but I've fixed it up, tested and applied it:

Comment 6 Neil Hanlon 2021-12-10 13:50:00 UTC 
Thank you for fixing up my patch. I should have tested it more thoroughly before sending it in.

With respect to your comment on the patch re: osinfodb -- Rocky should have support in future releases, if we aren't directly in there now: https://gitlab.com/libosinfo/osinfo-db/-/tree/master/data/os/rockylinux.org

Thank you again for your assistance with this patch.

Best regards,
Neil
Comment 7 Richard W.M. Jones 2021-12-10 14:22:10 UTC 
Thanks - I wonder if the osinfo short ID needs to be rocky%d.%d instead of
rocky%d ?

https://github.com/libguestfs/libguestfs/blob/1941593585574849dd72c458535cd80b4d858266/lib/inspect-osinfo.c#L52
Comment 8 Louis Abel 2021-12-10 16:26:00 UTC 
I believe that may be the case (rocky%d.%d vs rocky%d). Rocky uses major.minor in its /etc/os-release and /etc/rocky-release files, if that matters/helps.
Comment 10 YongkuiGuo 2021-12-24 11:50:53 UTC 
Test with packages:
libguestfs-1.46.1-2.el9.x86_64
guestfs-tools-1.46.1-6.el9.x86_64
qemu-kvm-6.2.0-1.el9.x86_64


Steps:

1. On rhel9 host
# virt-inspector -a /var/lib/libvirt/images/Rocky-8.5.qcow2
<?xml version="1.0"?>

The info is correct.
