600 seconds seams more than a reasonable time to create an empty DB,
if it requires more than 10 minutes for a simple/short operation there
is probably something strange with the storage.
I monitored the host RAM/CPU usage
and the utilization of the Ethernet
interface on the shared storage. RAM and CPU usage were minimal and
there was barely anything going through the network interface. I can
confirm that the network interface is fine as it is heavily utilized
when the engine setup uses it to copy the image to the storage. I'm not
sure what other statistics I should monitor to see if there's a bottleneck.

Yes, the engine VM host-name and its root password are configured via
cloud-init and there is not default password.
If you want to avoid using cloud-init you have to reset the root
password of the engine VM as for any el7 machine.

On failures, there is not just the engine VM disk but a whole storage
domain for hosted-engine which also contains ancillary disks.
Re-deploying over a dirty storage is not supported so please clean up
the whole storage domain on failures.

This is not hosted-engine specific:

Thanks for pointing out the BZ
ticket. I'm not entirely certain that's
the same issue I was seeing. Of course, I have no way of verifying
anymore as I have already re-deployed using CentOS instead of Node.

Are you running in a nested env?
No, this is bare-metal, not a nested environment.
