You are right here: we are not copying the host timezone to the appliance:
we can do it via cloud-init.
Good catch!

We will let you edit some of the engine VM parameters from the engine
itself.
All the modification will be saved as OVF file on a special volume called
OVF_STORE; when needed ovirt-ha-agent tries to get the up-to-date engine VM
configuration from there and if there is any issue it falls back to the
initial vm.conf from the setup time.
The issue is that by default OVF_STORE gets populated only after 1 hour and
so if you wait less than 1 hour you'll get that message since the OVF_STORE
is still not there.
