Hi Sandro,
We upgraded from 3.6 to 4.0 but it was still working after the upgrade. It broke when we did a restart.
Any ideas how to fix this?
Also, in case we can’t make it work can we save the VMs and reload them after a fresh install of ovirt? We don’t want to lose the data that is on the VMs. Is there anyay to recover the data in the VMs?
Thanks,

Not sure how you got there.
Can you share steps you did before having this issue?

Hi Sandro,
Thanks for your response.
We have tried that already but the VM shuts down after the –vm-start executes.
Also, apologies for wrong information bfore. We have 3 dedicated hosts not 1.
Please see below the output of –vm-status command:
Can you please share sos report or at least vdsm logs from the hosts?
Need to understand what happened to the vm.

Hello Ovirt Users,
I am new to ovirt.
Hi, welcome ot oVirt community!
Just trying to fix the issue with the engine which seems to be down and hence all our VMs which we are very much dependent upon are not working.
Other VMs shouldn't be affected by an unavailability of the engine, they should keep going if already started.
Tried googling the log snippet but to no avail. Hoping to get some help from you guys.
I am completely blank and don’t know whats wrong with it.
We have 3 Dell servers. One for Engine and the other two for nodes. Please see the log snippet from the engine server agent.log. Please let me know if more information is needed to debug the issue.
So you have only 1 host dedicated to running hosted engine?

Looks like hosted engine has been turned off at Tue May 30 17:18:38 2017 without moving to maintenance before doing it.
Above logs are timed 2017-05-30 17:22:24, so 4 minutes after the shutdown.
The agent should have already restarted it in a few minutes after above logs.
Next time, if you need to urgently bring it up again you can use:
hosted-engine ---vm-start
as described in http://www.ovirt.org/documentation/self-hosted/chap-Troubleshooting/
