Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 functionality will not make it into RHEL 7.2 scheduling.  Moving to RHEL 7.3.

Comment 12 Martin Tessun 2016-04-08 14:25:31 UTC 
As we have (again) a Conditional NAK upstream, is there any possibility to really get this done with RHEL 7.3?

We slowly lose credibility with the customer, as this feature was promised with RHEL 7.0 first, was delayed several times and was promised to be included in RHEL 7.3 latest.

This does not look to be the truth. In case I tell VWFS that again no ACPI based hotunplug of CPUs is available, they will really lose the rest of their trust in getting this feature at all, and will most probably start looking at different solutions then as well.

Any comments on the timeframe?

Thanks,
Martin
