Hello Dan, Options mainly as would like to start using SFlow down the line for protocol analysis across the VMs; plus GRE etc. Thanks, P. ----- Original Message ----- From: "Dan Yasny" <dyasny(a)gmail.com&gt; To: "Phil Daws" <uxbod(a)splatnix.net&gt; Cc: "users" <users(a)ovirt.org&gt; Sent: Tuesday, 7 October, 2014 2:29:39 PM Subject: Re: [ovirt-users] To oVirt or not to oVirt Why do you need OVS? oVirt supports VLANs out of the box without the extra hurdle On Tue, Oct 7, 2014 at 9:21 AM, Phil Daws < uxbod(a)splatnix.net > wrote: Would this be the way to integrate OVS http://www.ovirt.org/OVirt_Neutron_GRE_Integration_-_How_To ? or in 3.5 are you able to import OVS networks now ?

If you really intend to use that, you will need to install neutron with whatever plugins you need and use it as an external provider for the VMs. If this is just a matter of "I can haz this cool tech", but really, regular bridging with VLAN support, custom MTUs and a bunch of other features (especially a very easy graphical setup) are enough, I'd stick with oVirt native networking - it's pretty powerful in it's own right.

am reading through the release notes for 3.5 as I believe one can install the engine on a VM now.

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.

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.

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.
