found 1 way solve - turn off vm, turn on, it's annoying , danger.

did have issue before?

hello,

i've seen similar power settings in windows server 2008 r2 , latest intel processors.  this:

* disable c states in bios

* enable "high performance" power management on host systems

* apply patch: http://support.microsoft.com/default.aspx/kb/975530?p=1

* disable offloading on network cards

i hope helps out
