There's a fair bit we can get but as you say not the full picture.
However I'm pretty sure we can get patches into upstream QEMU to get
the rest, as with 'info blockstats' which had a relatively smooth
passage upstream.

  XML			QEMU command

  name			'info name' although this command
  			  seems to do nothing for me

  uuid			? - perhaps from socket name

  memory		not available (parse qemu command line?)

  vcpus			'info cpus'

  os/type		? - from process name or command line?

  os/boot		not available (parse qemu command line?)

  devices/emulator	process name

  devices/disk		'info block'

  devices/interface	'info network' (somewhat indirectly)

  devices/graphics	'info vnc' (I think)

Rich.
