Avi,This is the patch to enable PLE, which depends on the a small change of Linux scheduler
(see http://lkml.org/lkml/2009/5/20/447).
According to our discussion last time, one missing part is that if PLE exit, pick up an unscheduled vcpu at random and schedule it. But further investigation found that: 1. KVM is hard to know the schedule state for each vcpu. 2. Linux scheduler has no existed API can be used to pull a specific task to this cpu, so we need more changes to the common scheduler. So I prefer current simple way: just give up current cpu time. If no objection, I'll try to push common scheduler change first to linux. Thanks, edwin
