This is a self hosted engine composed by only one single host.
Normally I would use the procedure from the engine web admin gui, one host at a time, but with single host it is not possible.....

We have said several times, that it doesn't make sense to use oVirt on a single host system. So you either need to attach 2nd host to your setup (preferred) or shutdown all VMS and run manual upgrade of your host OS

We who????

In old times there was the all-in-one setup that was substituted from single host HCI ... developers also put extra efforts to setup the wizard comprising the single host scenario.....

Obviously it is aimed at test bed / devel / home environments, not production ones.

Do you want me to send you the list of bugzilla contributed by users using single host environments that helped Red Hat to have a better working RHV too?

Please think more deeply next time, thanks
