I'm just trying it, after reverting to snapshot of my VM that should work as single host HCI node.

So now no gluster configuration in place and second disk free to be configured by gui.

I select now the right box of Hosted Engine Setup page, the one with

" 

Hyperconverged

Configure gluster storage and oVirt hosted engine

"

Then select "Start" button.

In the new page I put the ip of second network adapter of host1 that I plan to use for gluster storage, but then I receive these warnings about host2 and host3, so that I cannot go ahead...

What to do?

Can you please open a bug against the cockpit HE wizard for that?

We do have to https://bugzilla.redhat.com/show_bug.cgi?id=1608660 and will be available in oVirt 4.2.6
