That question is:
 Add lines for the appliance itself and for this host to /etc/hosts on the
engine VM?
 Note: ensuring that this host could resolve the engine VM hostname is
still up to you

As Didi stated the properly way to use that is with a properly working
DHCP/DNS infrastructure having each host resolving each others and so on.
Then hosted-engine setup will ask you about engine VM mac address and you
have to create a reservation for that on your infrastructure.

For smaller/test deployment where a DHCP server is not present we are
providing also a static IP addressing option for the engine appliance:
you can specify an IP address for your new VM and it will be configured in
the appliance via cloud-init.
Then your host should be able to resolve it and so, if you don't have a
registering DNS,  it's up to you to configure it via /etc/hosts on your
host.

Cause the appliance deployment is fully automated you don't have the time
to do it on the appliance and so we provided a way to inject the host
address into /etc/hosts on the appliance.
It's still up to you to add other hosts there if you want to deploy
additional ones.
So having a properly working DNS and DHCP server is definitively a better
option.

1. Hit your screen prefix combination ( C-a / control + A by default), then
hit Escape .
2. Move up/down with the arrow keys to scrool the output buffer.
3. When you're done, hit Return twice to get back to the end of the scroll
buffer.

Depending from where it stopped it could be that you have to manually
destroy your previous empty appliance instance and cleanup its storage
before being able to retry.
