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
