I've just encountered this same unexpected behaviour (currently on RHEL7
box running libvirt 3.2), and found this thread while searching for a
bug report.
Has this patch been accepted, or the issue fixed in a later release? I
notice there was some confusion in the conversation following as to the
cause of this issue/the fix for it.
The problem with losing fcntl locks on execve was worked around in libvirt with
this patch series (included in libvirt 4.2.0)
https://www.redhat.com/archives/libvir-list/2018-March/msg00298.html
If not, is there a bug open against this which I can follow/comment
on?
There's an open bug to track the lost locks
