[Qemu-devel] [Bug 1502613] Re: [Feature Request] Battery Status / Virtual Battery
Tue, 07 Jun 2016 20:53:45 -0000
I'm trying to add virtual battery to QEMU. More specifically, if the
HOST is running on battery power [laptop] I want to pass this knowledge
I have looked at ACPI folder within QEMU source code, however was unable
to find the specific place where I can add this functionality.
Can someone provide me with general roadmap of what should I do and
where I should start? I suspect that changing the QEMU source code will
not be enough and I will also have to implement a driver for the GUEST.

[Feature Request] Battery Status / Virtual Battery
Status in QEMU:
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". 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 /
