Urgh, 16 characters is tiny :-( I think we had better add a configuration
parameter to /etc/qemu/qemu.conf to allow admins to turn this feature
on/off, with the default being off. At least until QEMU can support a
sensibly sized process name...

The patch looks fine, as long as you can add the qemu.conf config
param to turn it on/off
Sure, attached.
I tried to make some of the whitespace in the sample config more consistent;
hope that doesn't cause headaches.
