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.

+++ This bug was initially created as a clone of Bug #1678085 +++

'-numa node,cpus=' has some problems and will be deprecated by qemu in near future. And '-numa node,nodeid=xx' is recommended by qemu. So libvirt should implement to use '-numa node,nodeid=xx' for numa configuring.

If libvirt is to use -preconfig it needs to be stabilized first. There was an attempt on the list:

https://lists.nongnu.org/archive/html/qemu-devel/2021-11/msg00135.html

but the discussion got hairy and more complex solution was suggested.

Memo posted upstream: Redesign of QEMU startup & initial configuration>
https://lists.gnu.org/archive/html/qemu-devel/2021-12/msg00138.html

Instead of continually kicking the can down the road, closing deferred as discussions / work continues upstream and it's unclear whether it would be completed by the aging deadline.
