I=E2=80=99m running 3.6 with local NFS for the hosted engine. I have =
more than one host but they are all isolated and export they storage via =
local NFS. Setup has been running since 1 year now.

Maye you can give it a try?

Subject: [ovirt-users] oVirt on a single server

=20

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, 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.

=20

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.
