Hello,

has anybody found out if Windows does something similar as FreeBSD with 
kern.hz when running on a hypervisor?

I haven't done meaningful measuring, but on bhyve I see 2-digit CPU load 
with idle windows (2012R2) guest.
I never saw that on ESXi, it's much lower there, whil FreeBSD as guest 
on ESXi is even lower when idle.

Can somebody confirm this difference?
Is there a way to spoof hypervisor vendor string (from userland)? Resp. 
has anyone done that to see if windows behaviuor changes?

Thanks,

-harry
