By looking at your image, I found that this recognition discrepancy is due
to localization.
In English, Hosted Engine was displayed even in my environment.

Yes, I noticed this icon soon. It's very good.

Please use the engine web interface to deploy any additional hosts.'

I'm sorry I haven't tried cli install in 4.1.1, but I think it important to
restrict it as you said.
It was a great relief for me personally to automate setting such as lvm,
glusterfs, firewalld and selinux.

There are no particular points to improve.
Thank you for your support.
