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.

Fixed In Version: libvirt-0.10.2-19.el6
Doc Type: Bug Fix
Doc Text:
Prior to this update, the F_DUPFD_CLOEXEC operation with the fcntl() function expected a single argument, specifying the minimum file descriptor (FD) number, but was provided none. Consequently, random stack data were accessed as the FD number and a libvirt live migration could then terminate unexpectedly. This update ensures that the argument is provided in the described scenario, thus fixing this bug.

Red Hat Product Errata RHBA-2013:1581 0 normal SHIPPED_LIVE libvirt bug fix and enhancement update 2013-11-21 01:11:35 UTC

Comment 1 Eric Blake 2013-05-08 15:10:11 UTC 
6.5 will pick up the fix via rebase, but the problem is real enough to warrant a backport to 6.4.z.
Comment 4 yanbing du 2013-07-09 11:09:42 UTC 
Verify this bug:

#rpm -q libvirt
libvirt-0.10.2-19.el6.x86_64

Following the steps in bug description, do live migrate
# virsh migrate --live tsu-1 qemu+ssh://10.66.85.73/system --verbose
root.85.73's password: 
Migration: [100 %]

And the guest running on dest host, so move this bug to VERIFIED.
