A user starts a VM at a physical box. Everythings fine but he wants to

Users don't have boxes. They have computers. They don't want to open VNC
clients and type in meaningless numerical addresses.
A qemu gui can easily hide that it actually uses vnc. The only thing
needed is a connection to the monitor (you'll need that anyway to have
your fancy buttons do anything useful). The GUI can do 'info vnc' to
figure how to connect to the vnc server then.
It can't hide the inefficiency introduced by vnc. It doesn't matter for
cirrus, but it will matter with more powerful vgpus.
Even if you tunnel gpu commands on vnc, you still have to be able to
reconstruct your state on client disconnect. With a native client, a
disconnect is not posssible, so we can rely on client rendering.
They do want GUIs
which fit with the OSes theme, cut'n'paste, printing, and shared
storage, all easily configurable.
You mean something like virt-manager?
Like virt-manager, but with all the things I mentioned.
BTW: you can quit and restart virt-manager while your VMs keep running.
Sure, since we don't much care about graphics performance.
This cannot be achieved with a gui in the same process as qemu. Is it
necessary to support? I don't know.
In the priority list this is about 3000 places below having nice buttons
to eject and insert a CDROM. A user with a "box" would probably want to
run the guest on a server (and use vnc, etc.).
Focusing on the users needs *only* doesn't fly. You want have users
and hackers use the same thing, otherwise you'll have a hard time
finding developers for the GUI.
If that's so, we're doomed. If the only itches scratched are
deveopers', real users will be left out in the cold (or rather, in the
evil clutches of those who will scratch their itches).
Which in turn means placing the GUI into a separate process (which may
even run on another machine) is a must-have.
I don't see how this follows. How does catering to
developers/power-users imply that can't we have an in-process GUI?
We'll still have vnc for server deployments.
