Description Martin Perina 2014-03-24 05:11:50 UTC
Description of problem:

With power management configured, host will be fenced during kdump, making the crash dump useless.  Crash dumps are essential for diagnosing kernel issues.

oVirt 3.5 behavior to prevent host in kdump flow to get fenced is described at http://www.ovirt.org/Fence_kdump

Comment 1 Martin Perina 2014-06-30 13:42:43 UTC
I've added some notes about feature testing to http://www.ovirt.org/Fence_kdump#Testing

Comment 2 Ohad Basan 2014-07-01 13:20:37 UTC
Moving to POST. one patch is not merged yet

Comment 3 sefi litmanovich 2014-08-12 07:22:18 UTC
Verified with ovirt-engine-3.5.0-0.0.master.20140804172041.git23b558e.el6.noarch.

Test Run:

Comment 4 Sandro Bonazzola 2014-10-17 12:40:33 UTC
oVirt 3.5 has been released and should include the fix for this issue.
