Hmmm, one wonders how virtual machines map things like screen saving and
power saving. I know that Xen has suspension of a VM, and you would
think that the hypervisor scheduler would give less time to a VM
spending time in the idle loop.
Other hypervisors (KVM, VMWare, etc) should have similar characteristics.
In other words, there is no advantage trying to Save a Virtual Screen or
Conserve Virtual Power.
Why not just turn off screen saving and power management?
