Hi,
I'm running ovirt (4.0.4) with hosted-engine on a single host (replacing
a vmware-server system). I just had to reboot the system, and ran
through the sequence in this message from April 2014:
http://lists.ovirt.org/pipermail/users/2014-April/023861.html
to get the sytem back online, and the engine VM came up. But of course
none of my other running VMs came back. So I was trying to go in and
set them all as Highly Available so that ovirt would start them.
I logged into the ovirt admin interface, went to [Virtual Machines],
selected one of them, clicked Edit, then the High Availability
tab. However even though it's not greyed out, I cannot select the Highly
Available checkbox. Clicking on it just does nothing. So I cannot seem
to set them as highly available. So what am I missing?
Attached is a screenshot of what I'm seeing.
I'm connecting using Firefox on a Fedora-23 desktop, in case that makes
any difference?

AFAIK in order to use HA, you need to have configured power management
and another host in the same cluster (new versions also work with
another DC) which acts as a power gate.
ovirt ensures your vms run "HA" by being able to fence hosts when
they misbehave.
So if you got just one host, you can't fence, and you can't set vms as "H=
A".

AFAIK in order to use HA, you need to have configured power management

they misbehave.
So if you got just one host, you can't fence, and you can't set vms as
"HA".
Okay, so is there some way to tell ovirt to auto-start VMs? I thought the
way to do that was marking them HA. If that's NOT the case, then other
than manually writing a script using ovirt-shell to start the VMs when
e.g. the engine starts.... Is there some way to tell ovirt to start a VM
automatically when the system starts? (e.g. after a power failure)?
Thanks,

I'm afraid there is nothing builtin atm, so you must script your own
stuff.
I'm working on it. I've got all the infrastructure in place to do that.
Just need one more thing -- the ability to test when the engine is
actually operational.

I voted for https://bugzilla.redhat.com/show_bug.cgi?id=1325468 which is a
bug that you added as a reference to 1166657. I've commented in both.
I still haven't given up ;)
I'm actually surprised there isn't an autostart mechanism. I would have
considered that one of the first things to add. But I guess they don't
consider a "startup from scratch" use case.

actually operational.
For future reference, here's what I did. First, I set up a user and
permissions in ovirt UI. The user has Login and RUN_VM permissions. Then
I configured .ovirtshellrc with the user credentials (including password).
Then I created the following scripts (obviously you can set the VM names
and the wait-time between startup to your own settings).
Hopefully these scripts will help the next person who needs to solve this
problem.
