Testing oVirt...
-
Installing/testing oVirt 4.2.6:
- 3 node gluster (hyperconverged)
- this install is "nested" on a Fedora 28 host
-
I've loosey been reading the posts on this but what is oVirt? Is it just a management thing for KVM or is it and KVM based hypervisor in it's self?
-
I'm not using LV Cache, Compression or Dedupe, but it is available:

Think of it as the KVM equivalent of vmWare vSphere.
-
So would you only use it in a "cluster" of servers?

You can do a single node or 3 nodes. (nodes aka hosts)
Those are your typical setups. -
oVirt single node gluster install
In the next release (which will 4.2.7), you'll be able to deploy a single node install from Cockpit UI.

@fateknollogee That's awesome!

It's a cloud infrastructure software, I'd call it a cloud stack but there's a product named that... it's a competitor of OpenStack or Apache's CloudStack.

It's KVM management. It is not cloud, nor a hypervisor. Just a management console.

It's not a cloud, nor a stack. It's only one layer of a virtualization management "stack". The stacks include the storage, storage management, virtualization management, cloud components, etc. This is only the one piece. It lacks the pieces necessary to be cloud (autoprovisioning and API based access.)

It's not a cloud, nor a stack. It's only one layer of a virtualization management "stack".

It does have API based access and just because autoprovisioning isn't ready to go out of the box, doesn't mean it can't. You can easily create scripts that autoprovision resources and for example, VPSs using the API.

I'll agree to this.

I looked up the API and it looked like it was just for monitoring. They have a full provisioning API now?

Sure, all virtualization can be used to build cloud. But until you've built the cloud, what you have isn't cloud yet. Like Xen or KVM can be the power behind a cloud deployment. So can oVirt. But until the other pieces are there, they are still just building blocks, not the whole themselves.

I've only used and tested it in the context of being a cloud stack. Perhaps I'd be better off then with an actual cloud stack.
Thanks for the clarification.

What cloud system did you use it as a part of?

Yeah. I think they've had it for quite a while.
