How kvm handle extern interrupt when guest os is running

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
