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)
