There are plenty of other reasons to be running a single-host Hyperconverged deployment, in production. One of them is financial. Another is for small-scale production systems that don't have the space, finances, or other resources to run a 3-node system. Considering it a "toy" doesn't mean it isn't (or shouldn't be) a supported deployment.
Having a tested upgrade path from EL 7.x/Ovirt 4.3.x to EL 8 / Ovirt 4.4 running on a single system would be extremely useful in those situations. I do realize that any upgrade of a single-host system is rife with the dangers of a failed upgrade, and it requires downtime either way. However I feel an in-place (yum/dnf) path is "safer" than a "reinstall from scratch" path. So having a well-documented path would be ideal. Thanks! -derek PS: While I am LOOKING at expanding my 1-node system to 3, I don't see that happening any time soon. And even then, I would need to migrate my NFS storage to something more distributed like Gluster. So I suspect I would need to reinstall the self-hosted engine regardless to change its storage, and then I can migrate all existing VMs from NFS to Gluster.
