Hi,
I'm following the instructions here: http://www.ovirt.org/Hosted_Engine_Howto My self-hosted install failed near the end:
To continue make a selection from the options below: (1) Continue setup - engine installation is complete (2) Power off and restart the VM (3) Abort setup (4) Destroy VM and abort setup

I can ssh into the engine VM both locally and remotely. There is no /root/.ssh directory, however. Did I need to set that up somehow? It's the engine that needs to open an SSH connection to the host calling it by its hostname. So please be sure that you can SSH to the host from the engine using its hostname and not its IP address.
I'm assuming this should be a password-less login (key-based authentication?). Yes, it is.
As what user? root
OK, I see a couple of problems. First off, I didn't have my deploying-host hostname in the hosts map for my engine. After adding it to /etc/hosts (both hostname and FQDN), when I try to ssh from root@engine to root@host it is prompting me for a password. On my engine, ~root/.ssh does not contain any keys. On my host, ~root/.ssh has authorized_keys, and in it there is a key with the comment "ovirt-engine". It's possible that I inadvertently removed ~root/.ssh on engine while I was preparing the engine (I started to set up my own no-password logins and then thought better and cleaned up, not realizing that some prior setup affecting that directory had occurred). That would explain the second issue. How/when does the key for root@engine get populated to the host's ~root/.ssh/authenticated_keys during setup? -Bob

Till hosted-engine hosts were simply identified by their IP address but than we had some bug report on side effects of that. So now we generate and sign certs using host hostnames and so the engine should be able to correctly resolve them.
When I log into the Administration portal, the engine VM does not appear under the Virtual machine view (it's empty). It's cause the setup didn't complete.
I've attached what I think are the relevant logs.
Also, when my host reboots, the ovirt-ha-broker and ovirt-ha-agent services do not come up automatically. I have to use systemctl to start them manually. It's cause the setup didn't complete.
This is a fresh Fedora 20 machine installing a fresh copy of Ovirt 3.5.1. What's the cleanest approach to restore/complete sanity of my setup please? First step is to clarify what went wrong in order to avoid it in the future. Than, if you want a really sanity environment for production use I'd suggest to redeploy. So hosted-engine --vm-poweroff empty the storage domain share and deploy again
Thanks, Bob
