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 / ... ** Affects: qemu Importance: Undecided Status: New ** Tags: battery management power virtual -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1502613 Title: [Feature Request] Battery Status / Virtual Battery Status in QEMU: New Bug description: When using virtualization on notebooks heavily then virtual machines do not realize that they're running on a notebook device causing high power consumption because they're not switching into a optimized "laptop mode".
