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.

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 07:09:42 EDT
Verify this bug:

#rpm -q libvirt

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

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