If you're going to bother commenting on a big long email, please
_CHOP OUT_ content which is not relevant to your reply. I paged down 5
pages, hit end, paged up, found no comment from you, so I'm not going to
bother reading anything further in this message.

There is not point sending a new one.

From: Yang Zhang
Virtual interrupt delivery avoids KVM to inject vAPIC interrupts
manually, which is fully taken care of by the hardware. This needs
some special awareness into existing interrupr injection path:
- for pending interrupt, instead of direct injection, we may need
update architect
- APIC read doesn't cause VM-Exit
- APIC write becomes trap-like

basically to benefit from apicv, we need to enable virtualized x2apic mode.
Currently, we only enable it when guest is really using x2apic.
Also, clear MSR bitmap for corresponding x2apic MSRs when guest enabled x2apic:

APIC virtualization is a new feature which can eliminate most of VM exit
when vcpu handle a interrupt:
APIC register virtualization:
APIC read access doesn't cause APIC-access VM exits.
APIC write becomes trap-like.
Virtual interrupt delivery:
