Question 1: In General, can i install oVirt Node and hosted-engine on one physical server? Yes and single node hyperconverged is suggested for single node deployments.

Question 2: What domain names should I specify in the DNS server and which ones IP should I reserve? You can use any domain name you have ownership of and control the DNS for, as seen to and from your host and VMs not localhost.

You want two hostnames that resolve to the same network/netmask, one for the hypervisor, one for the engine VM. The installer will create a network bridge for the engine VM off the host's ethernet which the two will communicate over and it will be available for any other VMs you deploy later with that network.. This network must be reachable via your web browser, so it is usually a public network address, For updates, installation needs, etc. both host and engine will want to reach out to the internet. If you're planning on adding more storage servers, another network as a private network and hostname that resolves to it would be suggested, but it isn't necessary in the single host case.

Question 3: "Failed to connect to the host via ssh: ssh: connect to host ovirt-engine-01.local port 22: No route to host" - Who and where is trying to establish a connection via SSH? The host will try to ssh to the engine VM and the engine VM will will try to communicate to the host. The main accounts are root and vdsm. I'm not sure of others.

Can someone reply to questions 1-3 above? Any help will be much appreciated.

Thanks for the help, Ivan.
