Hello.
My Windows 10 VMs are 95% of the time idle. So i want to change the governor to save the power.
When i use performance governor then my CPU bound job in the VM works in 3.5s.
When i change governor to ondemand it works in 4.6s. And if i use conservative governor then it works in 6.7s.
I can see in cpupower monitor that frequency is not reaching its maximum by kvm process. But if i use for example stress utility on the host - the frequency reaches its maximum instantly.
I tried cpu pinning by taskset, but no luck.
Any ideas?
