Question about cold start
I have an oVirt cluster that was hard shutdown last night (fire is bad, and firemen killed the generators for their safety). When it came back up, it did not start any VMs other than the hosted engine. Is that expected? I know this is not a normal use case, but is there a way to set VMs to start on cluster boot? -- Chris Adams <cma@cmadams.net>
I believe you would accomplish this by setting a VM to be highly available (like the engine). Then engine makes sure this VM is up on at least one node through lease agreements (IIRC). In either case, I think this is what you want On Wed, Oct 4, 2017 at 10:25 AM, Chris Adams <cma@cmadams.net> wrote:

That keeps VMs up as long as the cluster is up, but does not bring them back if the whole cluster goes down (unless there's some other setting I'm missing). -- Chris Adams <cma@cmadams.net>
Hi,
That keeps VMs up as long as the cluster is up, but does not bring them back if the whole cluster goes down (unless there's some other setting I'm missing).
Unfortunately no, you are not missing anything. We do not have this functionality ATM. We have a feature request for exactly what you are asking for here: https://bugzilla.redhat.com/show_bug.cgi?id=1325468 Can you please describe your use-case there to make sure we do not forget and to make it obvious there is a need for this feature? Thanks Best regards -- Martin Sivak SLA / oVirt On Wed, Oct 4, 2017 at 6:04 PM, Chris Adams <cma@cmadams.net> wrote:
