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.

Comment 1 Gerd Hoffmann 2013-04-18 13:01:41 UTC
Backporting upstreqm qemu patches into rhel6 qemu-kvm triggers this on rhel6 too.
See bug #909059.

Comment 3 Paolo Bonzini 2013-04-18 13:13:56 UTC
In particular this is upstream QEMU is "emulating" child sources to run on older glib versions that do not have them.  It then triggers the finalize-from-finalize scenario described here => https://bugzilla.gnome.org/show_bug.cgi?id=626702#c6

Comment 6 Paolo Bonzini 2013-04-19 08:02:59 UTC
I think we'll have to find a workaround in QEMU anyway, but yes, ATM this is blocking the backport.

Comment 8 Colin Walters 2013-06-03 17:35:01 UTC
You want just that one patch backported to rhel6.5?

Note there is a rebase to GLib 2.26 scheduled from https://bugzilla.redhat.com/show_bug.cgi?id=883021 (as part of https://bugzilla.redhat.com/show_bug.cgi?id=883010 ).  So we'll need to validate the backport of glib 1f853c75ccb0a42757c3661ed36427e69e416af3 on top of 2.26.

Comment 9 Paolo Bonzini 2013-06-04 10:08:42 UTC
We worked around the bug in the meanwhile, but having the bug fixed would be useful anyway.

Comment 13 RHEL Program Management 2013-10-14 03:47:21 UTC
