See here https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/ If you want to avoid the backup/restore you can try reinstalling some of the packages: yum reinstall ovirt-engine-wildfly and run engine-setup.

I recommend you do an engine-backup, clean up the os (yum update, ensure proper ovirt repo for you version) and do engine-setup and restore.

I'm not sure if you're saying your entire engine doesn't work, or just host deploy doesn't work. What version of ovirt engine is this? How did you install -- fresh installation, upgrade? From source or rpm?
