Sorry, I missed the screenshots in your initial mail.

It looks like you are running gnome-system-monitor inside the VM, so it
is expected to "consume" some CPU for rendering gnome-system-monitor
itself (since GNOME Shell is a compositing manager).

It might be interesting to monitor your VM from the outside, using top
over ssh, without additional graphical applications causing screen
updates.
