</div></div>The majority of users on this list MIGHT be desktop users but Ubuntu's<br>
been a pioneer in developing and adopting cloud technologies and its<br>
the number one distribution, by far, on AWS.<br>
<br>
I've never tried to use Unity or Gnome Shell with KVM but I'll take<br>
your word that it wouldn't work because of missing OpenGL support.<br>
However Gnome has a GUI frontend for KVM called Boxes. I've never used<br>
it but its networking options are limited to basic slirp natting,<br>
which is only useful for a non-server, so they might/must have made<br>
Gnome Shell available via Boxes (with spice or vnc graphics?),<br>
especially given how keen they are to prmotoe their own stuff.<br>
<br>
But KVM is used heavily with Ubuntu in server rooms (I've worked on<br>
two 200-plus deployments in the last year), so calling it obsure is<br>
something of an exaggeration.<br>
<br>
The OP's style was ridiculous but he had a legitimate problem, albeit<br>
one that didn't apply to all KVM users because he was using KSM.<br>
