High Battery Drain

Post by Anunes »

Hi,
I have noticed that Guests are draining a lot of power.
Also, looking to the CPU usage on Host it stays at 100% even when there is no activity on the Guest.
Is there a way to configure VB to scale the CPU usage according to the activity of the Guest?

My guests run fine on my host. What's different between our setups? Maybe your guest? Or your host? Or mine?

Irony aside, unless you tell us in detail what's the host, what's the guest, what your settings are and what are the exact symptoms, I'm afraid you're going to be on your own...

You didn't list even the most basic and highly relevant facts, such as how you determined that "CPU usage on host stays at 100%" (100% of what? one core? all cores?), or that there is "no activity" in the guest. Especially the latter needs expanding on, because Windows is well known for keeping itself very very busy for long periods of time even (or especially) when the system is left alone.
