[ovirt-users] Re: hosted engine migration

I think that you can try to set one of the HE hosts into maintenance and then use UI to 'reinstall'. Don't forget to mark the host as a HE host also (some dropdown in the UI wizard).

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.

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.
