Hi,
I got this behavior once and I didn't tested again.
I started the hosted-engine deployment using cockpit webui, the process
went smoothly, the LocalHosttedEngine VM was created, at that time I left
the console for sometime.
When I get back the cockpit console was closed due to idle session timeout,
I reconnect, and the hosted-engine wizard had disappeared and I didn't find
a way to get it back, the only choice was to start the process again even
if the console was showing that the host was registered with a hosted
engine Manager, so I couldn't continue the deployment (the storage phase).
I had to stop the LocalHosttedEngine VM, delete it's temporary disk, then
restart the deployment again and this time I stick with cockpit webui to
get it done.
Regards.
