When I tried to put the host in maintenance in web UI, I got an error:
Adding Arik. Arik - any idea what else to test?
When I typed the command, I got this:
[root@node22 ~]# hosted-engine --set-maintenance --mode=local
Unable to enter local maintenance mode: the engine VM is running on the current host, please migrate it before entering local maintenance mode.
Sorry, I wasn't aware that this was disabled since 4.3.5, about a year ago: https://gerrit.ovirt.org/#/q/Ia06b9bc6e65a7937e6d6462c001b59572369fe66,n,z So you'll have to first fix migration on engine level. Best regards,

I have found some engine logs:

It seems that both of the two hosts were filtered out.
So please check cpu conf of the hosts, cluster, VM, etc.
One more thing you can try is to force putting the host in maintenance - this will require migrating the engine VM.
If the engine refuses to do that, because it can't migrate the VM due to above issue, you can try instead:
hosted-engine --set-maintenance --mode=local
I think this overrides the engine and will force a migration. Didn't try recently.

I could not find any logs because the migration button is disabled in the web UI. It seems that the engine migration operation is prevented at first. Any other ideas? Thanks!

I'm running oVirt 4.3.10 and I can migrate my Engine from node to node. I had one similar issue , but powering off and on the HE has fixed it.
You have to check the vdsm log on the source and on destination in order to figure out what is going on. Also you might consider checking the libvirt logs on the destination.

Thanks! The scores of all nodes are not '0'. I find that someone has already asked a question like this. It seems that this feature has been disabled in 4.3. I am not sure if it is enabled in 4.4.

Have you checked under a shell the output of 'hosted-engine --vm-status' . Check the Score of the hosts. Maybe there is a node with score of '0' ?
