Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Description RHEL Program Management 2011-01-18 08:10:41 UTC

This bug has been copied from bug #665293 and has been proposed
to be backported to 6.0 z-stream (EUS).

Comment 4 Jiri Denemark 2011-01-25 12:20:36 UTC

This is a FutureFeature and as such it is not suitable for Z-stream. The feature will only be included in RHEL-6.1.

Comment 5 Michael S. Tsirkin 2011-01-25 12:26:56 UTC

It's a feature but it enables a work-around for qemu bug which we can't enable
otherwise.

Comment 6 Dave Allan 2011-01-25 20:26:37 UTC

I don't think we can reject this BZ for z-stream without further discussion of the issues.  It appears to me that this is a workaround for a significant problem.  If it's possible to fix the underlying problem, we should do so, but if the only option is for libvirt to provide a workaround, then it is appropriate for z-stream.  MST, can you provide a high-level summary of the problem and why you think working around it in libvirt is our best option?
