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.

Comment 1 Eric Blake 2013-05-08 11:10:11 EDT

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
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@10.66.85.73's password: 
Migration: [100 %]

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