Yes, if you have the source, you can directly check it., otherwise, decompile kvm.ko, because apic_clear_isr() is inline function, which is called by apic_set_eoi(), you can check it, this method is a bit complicated. Any better ideas?

You can gain performance promotion from it, not too much, but it also depends on the frequency of access to above three apic regs.

Re: Windows 7 VM BSOD
Sure, but I am little confused as KVM is part of linux kernel now, if I want to try it, should I just upgrade kernel or compile kvm kernel module by myself ?!

Re: Windows 7 VM BSOD
what does vapic affect Windows 7 at all if I disable it? if it just a minor performance drop, I am fine with that.

Re: Windows 7 VM BSOD
I see, so it's minor performance gain, and not stability related option which is good. I am checking http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.5-trusty/, changelog showing lsr function is included, but when I download and extract kvm.ko out then run nm kvm.ko | grep lsr, nothing found.
