hosted-engine-setup probably failed adding the LUN to the engine cause it
was already there or something similar; we need engine logs to better
understand but the result is that it didn't completed creating the storage
volume.
Probably it's not worth to fix it cause we are going to remove that once we
completed the procedure to auto-import the hosted-engine storage domain.
didn't you noticed that it failed? wasn't the output clear enough?

Then the setup generates a temp file under
/var/run/ovirt-hosted-engine-ha/vm.conf to use it for the first run and it
copies to the shared storage for other hosts and further runs.
But it failed for the issue above before being able to copy it to the
shared storage.

Your local  /var/run/ovirt-hosted-engine-ha/vm.conf  simply survived till
you rebooted the host and so you were able to reboot the engine VM. As
expected it disappeared once you rebooted.
Probably the agent should validate the conf volume more strictly and fail
more clearly in this case so you'd notice it before.
I'll open a bug against that.

If you want to manually fix in order to recover your setup I can give you
the instruction set to manually create the configuration volume on the
shared storage.
If it was just an evaluation I'd suggest to redeploy it from scratch.
