[ovirt-users] Re: infrastructure boostrap. (i.e engine start / autostart).

Hi, I checked the self-hosted doc and I see that High-Availability is provided by additional "self-hosted" capable hosts and a dedicated shared Storage Domain to store the engine VM. What about the "upgrade-gone-wrong" case ? I mean, before any important upgrade of any VM, we take a snapshot and revert to it if required. We had a similar case when upgrading the engine from 4.3 to 4.4, where a mismatched cluster CPU type prevented starting VMs. We were even working with two different engine VMs rather than snapshots because 4.3 was on OL7 et 4.4 is on OL8. We had to revert for a while to the 4.3 engine waiting for the fix. What's the plan w/ a self-hosted engine ? *Laurent Duparchy* *ESRF - The European Synchrotron MIS Unit 04 76 88 22 56* Michal Skrivanek wrote on 04/11/2022 15:43:
