Hello
I want to install oVirt virtualization software on my ArchLinux as a lab for learning and
experimenting.
I'm having trouble going through the documentation because I don't understand how
the different pieces fit together.
Specifically, what are the roles of the oVirt Node, oVirt Host and oVirt Engine?
Thanks
3:30 p.m.
So in the documentation it says that the oVirt Engine is a user interface and a REST API
endpoint. Ok, that's clear enough.
As far as the oVirt hosts there are two types Enterprise Linux hosts and oVirt Nodes. Do
the Enterprise Linux hosts run the VMs for my apps or the oVirt nodes?
What are their respective roles? Do I need both?
10:51 p.m.
oVirt node is a dedicated hypervisor imgbased installer distro for oVirt
that handles upgrades all at once with a rollback feature, whereas an
Enterprise Linux Host would do the same thing but you would partition your
disks however you saw fit and manually install RPMs to get the same
functionality as a node-ng host. No need to have both type of hypervisor
hosts. The engine is sometimes a VM itself which provides the Web GUI and
databases needed to manage a cluster of virtualization hosts and VMs
therein.

Hi Edward.
"Therein" meaning inside the engine? The virtualization hosts run inside
the engine not inside the hypervision/Ovirt-node? And just to make sure,
the virtualization hosts are the VMs that ultimately run the apps?
Thanks

The hosts run the vms. The engine just basically coordinates everything.

New subject: What do some of the terms mean in the documentation?
Hi,
ovirt has 2 types of systems:- Hypervisor- Engine
The ovirt Node is a kind of appliance that works as a Hypervisor. You can also use Linux
host with the necessary repos and software.
The engine is a physical/virtual system that can contain the engine , which is the brain
of the solution, and several databases (which can be moved away).
The most used case is a Hyperconverged setup (hosts should be multiple by 3) where :-
Gluster (a network distributed ) is running locally and provides shared storage- oVirt
vdsm (host software receiving commands from the engine) is taking care for engine- Hosted
Engine - a VM that is running on one of the hosts and will serve as an Engine
