Ok here are the results when following your guide.

- Emulated machine: pc-1.0

- maintenance/activate one node of the cluster: - Emulated machine is still: pc-1.0 I guess that is nothing you wanted to see. So I changed the CPU type of the cluster and was able to understand what you think of. The emulated machine will go blank. After reactivating a node the value goes back to pc-1.0 I played with the cluster settings in between and cannot say if the value was empty when the error occured. Just in case the emulated machine value was empty during restart of ovirt-engine. Did I loose the machine because of that?

As I'm testing that is no problem but I want to make sure if I can recover from that situation in any way. Best regards. Markus
