Thanks - makes sense.
I've worked on this a bit more and have pushed a bit further, but from
looking through my new log, it looks like the engine is error-ing out
because my engine FQDN is cannot be resolved to an IP address.
*The error: *
[ ERROR ] Host name is not valid: *engine.example.rocks* did not resolve
into an IP address
*engine.example.rocks* is the FQDN I supplied when answering the following:
Please provide the FQDN you would like to use for the engine appliance.
> Note: This will be the FQDN of the engine VM you are now going to launch.
> It should not point to the base host or to any other existing machine.
> Engine VM FQDN: (leave it empty to skip):
*My /etc/hosts file: *
192.168.1.44 host.example.rocks host
192.168.1.45 engine.example.rocks engine
I can see why it's erroring, but I'm not sure what I need to do now to get
it working. The IP 192.168.1.45 is one I just made up, because the only
system I have access to is the one I'm currently using (192.168.1.44)
