Hi,

currently kernel config have
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y

set by default

This is used to use cpufreq userpace tool (not used in proxmox), to manage the cpu governor.

Myself , I always setup manually in my bios value to max performance,

because if not, it can give some dynamic memory or cpu frequencies change, and vms can crash (mainly windows guest)

see an report here: http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273


I think we should setup

CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y 

by default, to force it



What do you think about it ?
