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.

Description Pat Riehecky 2022-03-14 16:15:22 UTC
+++ This bug was initially created as a clone of Bug #2063922 +++

Description of problem:

Currently it is trivial to start numad on systems that do not actually have numa awareness.  This includes a number of virtualization solutions.

Version-Release number of selected component (if applicable):numad-0.5-35.20150602git.fc35.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Fire up a VM without numa nodes
2. start numad
3. it runs but can't do anything causing wasted CPU/Memory

Actual results:

The numad.service starts on systems without numa nodes

Expected results:

The service is able to detect if numa is not present

Additional info:

This patch alters the requirements to ignore starting numad on systems where there are not nodes to migrate between.
