Comment 1 Fabian Deutsch 2015-06-30 07:55:47 UTC 
I've tested that attached patch as follows:

1. Boot RHEV-H 6.7 (0609)
2. remount / rw
3. add upstart file and apply the patch
4. remount / ro
5. vdsm-tool configure --module libvirt --force
6. initctl status libvirtd
libvirtd start/running, process 15129
7. killall libvirtd
8. initctl status libvirtd
libvirtd start/running, process 16922

A new libvirt instance was spawned, to me this looks as if the bug is fixed with this and the Node side patch.
Comment 3 Jiri Belka 2015-07-09 09:06:36 UTC 
ok, vdsm-4.16.21-1.el6ev.x86_64 (rhevh6 20150707.0.el6ev)

Jul  9 09:05:12 dell-r210ii-04 init: libvirtd main process (14898) killed by KILL signal
Jul  9 09:05:12 dell-r210ii-04 init: libvirtd main process ended, respawning
Comment 4 Yaniv Bronhaim 2015-07-09 09:29:53 UTC 
After host reboot it won't work well with current vdsm code - Jiri, you can verify it as well and re-open for 3.5.5
Comment 5 Jiri Belka 2015-07-09 11:40:20 UTC 
As mentioned in #4, libvirtd is not running when killed after the host was rebooted.
Comment 6 Yaniv Bronhaim 2015-07-29 08:24:12 UTC 
This issue was raised by us when we found that RHEVH never ran libvirtd service with the upstart script - in 3.5.4 the fixes around it raised many regressions, in addition to that, this issue never came up as a bug by ovirt users so it can't be important enough to break other flows. I suggest to avoid this fix for 3.5. 
In next release which doesn't support el6 this issue is not relevant at all. 
I'm closing the bug unless someone thinks it worth fighting for.. If so, please review my suggested patch https://gerrit.ovirt.org/#/c/43227 and reopen the bug.
