Hi,
Is there any way to generate a VMExit for software interrupts?
I am interested in causing a VMExit when Int 80 instruction is executed in guest VM. Is it possible to do so? If so how?
Thank You

Neither vmx nor svm support trapping on software interrupts. You might
be able to track changes to the IDT and install a hardware breakpoint on
the int 80 handler, but that's quite difficult and hacky.
