Hello,
I'd like to ask, are there any recommendation about kernel timer frequency
for guest and for the host?
I guess that on host, the higher frequency can be better, but for guest,
100HZ should be better because it causes lower overhead for host, right?
Thanks a lot for reply in advance
cheers
nik
