Hi, I've been working adding support for split IRQ chip mode in QEMU. http://lists.gnu.org/archive/html/qemu-devel/2015-11/msg00235.html That work uncovered a few problems in the KVM implementation: * There's a missing call to kvm_make_request in kvm_vcpu_ioctl_interrupt. * req_int_win isn't set correctly in vcpu_enter_guest. * ready_for_interrupt_injection isn't set correctly in post_kvm_run_save. The following patches address those problems, and with those applied I'm able to boot Windows and pass the KVM unit tests. Any feedback is appreciated.
