IIRC we only suggest to update /etc/hosts of the engine, not the host.

Ok, I will crosscheck the output...

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.

I run it through screen and I'm not able to scroll through the output of it....

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.

Yes.

What is the supposed command for using answer file?

hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-20151021154529.conf

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.

What should have it put the generated output file? It seems there is nothing under /etc/ovirt-hosted-engine

[root@ovc71 ovirt-hosted-engine-setup]# ll /etc/ovirt-hosted-engine
total 4
-rw-r--r--. 1 root root 222 Oct 15 10:37 10-appliance.conf

[root@ovc71 ovirt-hosted-engine-setup]# cat /etc/ovirt-hosted-engine/10-appliance.conf
description=The oVirt Engine Appliance image (OVA)
version=20151015.0-1.el7.centos
path=/usr/share/ovirt-engine-appliance/ovirt-engine-appliance-20151015.0-1.el7.centos.ova
sha1sum=010c974c81aa45560002b0e3dfdf56fc81e31eb4

AH ok.. I found it under
/var/lib/ovirt-hosted-engine-setup/answers/answers-20151021154529.conf

So it remains the question regarding syntax for using answer file..

Thanks,
Gianluca
