Gianluca, after reinstalling the host with 4.4.8 ISO, did you update the ssh fingerprint of the fresh install within the ovirt engine? I'm assuming you didn't remove the host before reinstalling it and you didn't re-attach it to the engine after the upgrade.


No, I didn't do it... I would expect oVirt to manage it... 
Can I do it now?
If I try to do I get:

Error while executing action: Cannot switch Host to Maintenance mode.
Host still has running VMs on it and is in Non Responsive state.

because the temporary engine is on it

It seems in 4.2 -> 4.3 update it was not necessary...

Also, for example on RHV guides I see:
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html/upgrade_guide/she_upgrading_from_4-3

"
When upgrading Red Hat Virtualization Manager, it is recommended that you use one of the existing hosts. If you decide to use a new host, you must assign a unique name to the new host and then add it to the existing cluster before you begin the upgrade procedure.

and

Install RHVH 4.4 or Red Hat Enterprise Linux 8.2 or later on the existing node currently running the Manager virtual machine to use it as the self-hosted engine deployment host. See Installing the Self-hosted Engine Deployment Host for more information.
Note

It is recommended that you use one of the existing hosts. If you decide to use a new host, you must assign a unique name to the new host and then add it to the existing cluster before you begin the upgrade procedure.

  • The deployment script automatically disables global maintenance mode and calls the HA agent to start the self-hosted engine virtual machine. The upgraded host with the 4.4 self-hosted engine reports that HA mode is active, but the other hosts report that global maintenance mode is still enabled as they are still connected to the old self-hosted engine storage.

  • Detach the storage domain that hosts the Manager 4.3 machine. For details, see Detaching a Storage Domain from a Data Center in the Administration Guide.

    no mention about ssh fingerprint reissue

    Any hint on how to do it?
