Subject: Re: Enhancement for PLE handler in KVM

Thanks, Paolo for the comments

Understand the requirement to "fix it for all guest OSes".

I will investigate the "new hypercall KVM_HC_HALT_AND_YIELD_TO_CPU that 
takes an APIC id, donates the quantum to that CPU, and puts the 
originating CPU in halted state. "

Regards
Bin
