The OVF_STORE volume will contain the engine VM description in a format
that the engine can easily handle.
It will be created by the engine when:
- it imported the hosted-engine storage domain
- the engineVM is visible
- the datacenter is up (you need at least one additional regular storage
domain)

Please make sure that all these conditions are met.

If the OVF_STORE is not there or it's not accessible, ovirt-ha-agent will
fallback to the initial vm.conf from deployment time. You see a warning
since we are failing back to an initial status and this can temporary
override your latest customization to the engine VM configuration.

Please revert it.

It's just a side effect of your point 1, please revert it.
