Subjectkvm & dyntick
It occurs to me that kvm could benefit greatly from dyntick:

dyntick-enabled host:
 - generate virtual interrupts at whatever HZ the guest programs its 
timers, be it 100, 250, 1000 or whatever
 - avoid expensive vmexits due to useless timer interrupts

dyntick-enabled guest:
 - reduce the load on the host when the guest is idling
   (currently an idle guest consumes a few percent cpu)

What are the current plans wrt dyntick?  Is it planned for 2.6.21?
