i didn't understand how kvm handle extern interrupt when guest os running. i think the extern interrupt will cause vm exit, then kvm should pass this interrupt to host os , then the host os handle it. but i didn't found the correlative code.I think vmx_complete_interrupts and vmx_handle_exit function will be execute, but i didn't found how pass the extern interrupt to host os. If anyone knows , please tell me,thanks.
The interrupt causes a vmexit but is not consumed by the processor. Instead, it remains pending. As soon as the host enables interrupts the interrupt will be delivered.
