For what it's worth we do active passive with pacemaker, corosync, and drbd. all the configuration files stay synced by drbd, pacemaker ensures the services are only running on one node. Works pretty well.

For more demanding scenarios there is also an ansible role to handle the disaster recovery of an oVirt environment:
https://github.com/oVirt/ovirt-ansible-disaster-recovery

Here a demo about how to handle the mapping between the two sites: https://youtu.be/mEOgH-Tk09c

is it good enough to disable the ovirt-engine "systemctl disable ovirt-engine"  on the standby node? 
if it does, what about the other services, do I have to disable the following as well? : 
ovirt-engine-dwhd.service                     enabled 
ovirt-engine.service                          enabled 
ovirt-fence-kdump-listener.service            enabled 
ovirt-imageio-proxy.service                   enabled 
ovirt-provider-ovn.service                    enabled 
ovirt-vmconsole-proxy-sshd.service            enabled 
ovirt-websocket-proxy.service                 enabled 

Thank you!

HA hosted-engine cannot help if VM image are broken. HA runs same image
on different nodes, and if current running VM corrupt FS, for example,
it cannot  run on other nodes also.

I wrote about this experience here some time ago.
