My current understanding is that oVirt no longer supports any
single-server
configuration since the All-In-One install was removed in 3.6. While the
hosted-engine install was supposed to replace it, it requires either
networked storage (nfs, iscsi) or Glusterfs. To my knowledge nfs/iscsi
exported to localhost is not supported,
nfs exported to localhost may be fragile. iscsi server on your single host
should work.
The best option for single host is local storage, but I don't know if hosted
engine supports it.
so I would need at least 2 machines.
Furthermore Gluster requires at least 3 sources of storage for quorum (it
would be great if there was an option to acknowledge the risks and
continue), meaning a single machine is not practical.
You can use single glusterfs brick, I think it should work wit hosted engine
setup.
I understand and acknowledge that oVirt is not targeted towards
homelab
setups, or at least small homelab setups. However I believe that having a
solid configuration for such use cases would be a benefit to the project as
a whole. It allows oVirt to be much more visible in the homelab community,
and more accessible to testing which in turn yields more people who have
experience with oVirt. As it stands most other virtualization products
allow for usage (not just a livecd) in a single server environment, although
not all features can be used of course. vSphere, Xenserver, Proxmox, FIFO,
and Nutanix all allow an installation on a single server. It appears that
oVirt/RHV is the odd-one out - and it honestly shows when you look at what
people talk about online - there is a huge gap between even Proxmox and
oVirt when it comes to mindshare in the tech community, and it does not
favor oVirt.
I agree that it would nice if the all-in-one option was still available, but
someone has to maintain this setup.
For single host, better use virt-manager. You can import the vms later to
ovirt when you want to scale your lab.
If you want to experiment with ovirt, you can use virt-manager to create
several vms - if you enable nested kvm, you can use the vms as your
hosts. This is the standard setup we use for development.
