Hi,
sorry for jumping late on an old thread, I'm the one reporting that bug.
I have two things to say:
- taking advantage of a rare opportunity to turn off my production
cluster I put it back in that critical situation and I can confirm
that with oVirt 3.4.1 the problem has been solved.

> PS : I see no 3.4.1 update on CentOS repo.

- me too, until I installed ovirt-release34.rpm (see
http://www.ovirt.org/OVirt_3.4.1_release_notes ). All went smooth
after that.

Best Regards,
Giorgio.
