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.

Can you please elaborate on this? Why does IBM need this feature in RHEL? AFAIK, they have access to RHEL-AV where the feature already exists among with its fixes. What problem is IBM trying to solve?

The keyword FutureFeature has been added. If this bug is not a FutureFeature, please remove from the Summary field any strings containing "RFE, rfe, FutureFeature, FEAT, Feat, feat".

Since the needinfo wasn't answered in ~6 months I assume it's not that critical and thus I'm moving this to RHEL-8.6.0 where the feature will be picked up by rebase. Moving to POST then.

Test pass with libvirt-7.8.0-1.el9.x86_64 on jenkins. Set the bug to be verified.
