I had the label for reporting the auto-detect result, but I guess we
could just push the auto-detect result into the search field text box.
Would also need to auto-fill the text box with the full match when we
select a distro.

Yeah, we should definitely make an effort to fill in missing EOL info.
Mostly just requires searching wikipedia IME, sometimes the vendor's
own website.

Might be nice to display the short-id in the list too, if we're
matching on that ?

There is a "Generic" entry that appears in the list, presumably something
added by virt-manager thoug, since that's not part of the osinfo DB. Users
have to know to search for that though. I was trying to avoid adding special
cases to the list searching UI.

Perhaps the search field should always default to "Generic" as a starting
point if the user has not entered anything, or if auto-detect fails. That
would eliminate the codepath of having no OS selected entirely.
