IIRC something similar was reported on the lists - that you can't
(always? easily?) migrate VMs between CentOS Linux 8 (.3? .4? not
sure) and current Stream. Is this mandatory for you? If not, you might
test on a test env stopping/starting your VMs and decide this is good
enough.
Of course I tried, instead of migrating the VMs, simply stopping them on the Centos 8.5
hosts and starting them on the Centos Stream 8 host. It did not work, the network was not
reachable but there was no error thrown in the engine appliance, no event, nothing.
Perhaps provide more details, if you have them. Did you put host3 to
maintenance? Remove it? etc.
With everything I performed host3 was put into maintenance first. It has not been removed.
I planned to remove it but then the error below (Unable to start ovirt-ha-agent on all
hosts) started appearing.
Not sure where 'GATEWAY_IP' comes from, but it should be the
actual IP
address, e.g.:
I just replaced the actual gateway IP in the error message thrown with
'GATEWAY_IP', since the error message thrown does expose the gateway IP instead of
the respective host IP. This issue does confirm that finding:

Check (and perhaps fix manually, if you can't/do not want to first
diagnose/fix your reinstallation) the line 'gateway=' in
/etc/ovirt-hosted-engine/hosted-engine.conf . Perhaps compare this
file to your other hosts - only the line 'host_id' should be different
between them.
Everything in /etc/ovirt-hosted-engine/hosted-engine.conf is as you describe it. Only the
host_id is different. I haven't touched that file either.
