Mmm, how can you know if it is injected successfully?
From the patch, it looks like you know this by checking
IDT_Vectoring in next VM Exit. That means the virtual
interrupt controller state in memory is incorrect temply.

One of the optimization, which can be used in pure SW is that
we can shadow APIC state as RO to guest so that all guest
read to APIC registers can run in full speed. T
This can still be done with unacked interrupts: modify the

With 2nd thinking, We can cache these 2 pages. Something like:

and for injecting interrupts in big real mode.
Interesting work. Do you have an updated tpr optimization patch which
applys on top of these patches?
