After we optimize the MSR/VMCS register save/restore to skip for those lightweight VM EXIT (handled by KVM). Giving up preemption disable in kvm_resched means we need to do a full context restore for host which is architecture specific.
Actually I am thinking to totally give up kvm_resched and just let control return to Qemu which is much clean and provide Qemu more chance to handle some kind of hardware event such as network packet arrive etc. Today Qemu is totally depending on heavyweight VM Exit to handle those events and virtual IRQ injections which may be not sufficient.
