Re: [ovirt-users] To oVirt or not to oVirt

Appreciated Daniel. If add more hosts down the line may the engine configuration be migrated back to a VM for resilience ?

Indeed, this is called Hosted Engine. In 3.5, witch is expected to be released in a few days/week you can also use a prebuild virtual appliance for this purpose. Also, the ovirt Node, witch is a prebuld minimal OS, will have the feature to support Hosted Engine. If you are running only one host, I would advice deploying more hosts or take the traditional approach and put the engine in bare metal box for production. Maybe you stumbled over the admin guide [1] already? The doc is quite new and reflects oVirt 3.4 Keep in mind, EL7 is sopported as HOST in 3.5 only atm, your Engine still needs to run Fedora 19 / EL6.5 > As I only have one server at present my thoughts are to install CentOS7, then oVirt 3.5 node (vdsm), and then create a VM which would be the oVirt Engine. There is a script, called hosted-engine --depoly for that. All you need to do is to enable the repos in yum and install ovirt-hosted-engine, desirably from a minimal install. Please read [2]. > Then as I add on another server I can just build that as a node and the Engine can be moved between. Is that correct ? Thanks, P. Also, for testing you can use ovirt all in one [3]. This is a HV host plus engine (but not as a VM IIRC). I would not recommend this for production.
