Hi all, I've set up an infrastructure with OVirt, using self-hosted engine. I use some ansible scripts from my Virtualization Host (the physical machine), to bootstrap the hosted engine, and create a set of virtual machines on which I deploy a k8s cluster. The deployment goes well, and everything is OK. Now I'm doing some reboot tests, and when I reboot the physical server, only the hosted-engine vm is up after the reboot, the rest of VMs and thus the k8s cluster are down. Had someone here ever experienced this issue? What can cause it and how to automate the virtual machines startup in RHVE/Ovirt? Thanks.

I was looking if the "High Availability" option could be used for automatic startup, but Ovirt documentation is pretty clear about it as explained here <https://www.ovirt.org/develop/ha-vms.html> you the documentation in the screenshot. I was wondering if there may be a flag that controls the VMs startup behavior... Le mer. 29 janv. 2020 à 12:07, Jayme <jaymef@gmail.com> a écrit :

Hello, It's my understanding that the engine will make every attempt at restarting highly available VMs. All of my VMs are highly available and none have never not started after rebooting hosts. On Wed, Jan 29, 2020 at 9:28 AM Eugène Ngontang <sympavali@gmail.com> wrote:

There is an important distinction though, if your reboot process involves shutting down the VM's cleanly - then rebooting the server - they will not auto start - however if their operation was interrupted and they are listed as Highly Available, then they will be automatically restarted. I believe they are working on a proper clean shutdown/ auto start procedure so you can order which VM's come up first and have wait times etc but its been coming for a while.

Indeed. And finally coming in 4.4. The order is not entirely customisable, but you can use priorities and group VMs so you can have some started before others But still if you shut them down cleanly they won’t come up. It would make shutting them down impossible if we always intervene and immediately start them up. Thanks, michal
