Hi Martin.

I have a stupid question. Use Watchdog device mandatory to automatically start a virtual machine in host Fencing process?

Hello oVirt guru`s !

I have oVirt Hosted Engine 4.0.3-1.el7.centos on two CentOS 7.2 hosts (HP ProLiant DL 360 G5) connected to shared FC SAN Storage.

1. I configured Power Management for the Hosts (successfully added Fencing Agent for iLO2 from my hosts)

2. I created new VM (KOM-AD01-PBX02) and installed Guest OS (Ubuntu Server 16.04 LTS) and oVirt Guest Agent
(As described herein https://blog.it-kb.ru/2016/09/14/install-ovirt-4-0-part-2-about-data-center-iso-domain-logical-network-vlan-vm-settings-console-guest-agent-live-migration/)
   In VM settings on "High Availability" I turned on the option "Highly Available" and change "Priority" to "High"

3. Now I'm trying to check Hard-Fencing and power off my first host (KOM-AD01-VM31) from his iLO (KOM-AD01-ILO31).

Fencing successfully works and server is automatically turned on, but my HA VM not started on second host (KOM-AD01-VM32).

These events I see in the oVirt web console:

Sep 15, 2016 12:08:13 PM        Host KOM-AD01-VM31 power management was verified successfully.

Sep 15, 2016 12:02:32 PM        VDSM KOM-AD01-VM31 command failed: Heartbeat exeeded
Sep 15, 2016 12:02:04 PM        VM KOM-AD01-PBX02 is down. Exit message: User shut down from within the guest


What am I doing wrong? Why HA VM not start on a second host?
