Hi Paolo, Thanks for your comments. I'll address your comments and submit two separate patches.

We discovered a couple of kernel issues in the split IRQ chip case: * 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. I'm testing a small patch and we expect to submit that soon. With fixes to those problems we're able to boot Windows and pass the KVM unit tests. Thanks, Matt
