This leads to the circumstance that they are trying to do things like defragmentation / virtus scan / etc. while the host is still running on batteries. So it would be great if QEMU / KVM would have support for emulating "Virtual Batteries" to guests causing them to enable power-saving options like disabling specific services / devices / file operations automatically by OS. Optionally a great feature would be to set virtual battery's status manually. For example: Current charge rate / charging / discharging / ...
