I'm trying to find the stable / current oVirt-live ISO to download.

According to the official documentation, it looks like there is only the legacy 4.1 ISO, or nightly / unstable builds of 4.2(.2?)?


I'm hoping we have deprecated it. For demo purposes, you could set up ovirt-system-tests[1]. For an all-in-one you could either install the Engine and the hypervisor on the same physical host, or a self-hosted-engine with a single physical node.

Alternatively, if one is to deploy the 'self-hosted-engine' on top of CentOS 7.4, the documentation doesn't make it clear what you should vs shouldn't setup on the host prior to deploying the hosted engine.

For example, some big questions pop up around networking, e.g.:

- Should I be setting those up during CentOS's install using the installer (which I believe configures them with Network Manager), or should I be setting up the ifcfg files manually by hand without touching Network Manager via the server's remote console after the install has finished?

Either is fine.
 

- Is it OK for me to setup my first two NICs in a mode 1 (A/P) or 4 (XOR) bond (these are connected to a 'dumb' switch and provide internet access and later will be used for management activities such as vm migrations).

It is, though if not needed, I think it's easier to do it later via oVirt.
 

- Is it OK for me to setup my second two NICs in a LACP bond (required as they connect to our core switches) and to add VLANs on top of that bond, include the storage VLAN required for iSCSI access which is later required to host the hosted-engine?

It is, though it might be easier to do it later via oVirt (unless you need it to access the storage Hosted-Engine is using!)

I think the hardest thing is that the documentation for oVirt seems very poorly maintained, or it's at least scattered around various links or different guides.

Our documentation, like the code, is open source. Patches are always welcome.


Perhaps this isn't obvious to people that are already familiar with the components, terminology and setup practises of oVirt / RHEV, but for someone like me coming from XenServer - it's confusing as anything.

With iSCSI, I prefer multipathing, but I see why you'd want bond, if it's used for other traffic as well.
