Trying to passthrough intel integrated gpu, display stays blank.

I'd like to passthrough my haswell integrated intel gpu to my emulated windows 7 installation.
On the real machine i use another gtx1050, so the intel card is left untouched (and stub is applied).


I followed the instruction here:
https://wiki.archlinux.org/index.php/PC … h_via_OVMF

All is working fine, except that the integrated intel gpu can't see any monitor.
Here:
https://git.qemu.org/?p=qemu.git;a=blob … assign.txt

...there are some requirements:

1    * IGD must be given address 02.0 on the PCI root bus in the VM  <<<---- met, did it manually
2    * The host kernel must support vfio extensions for IGD (v4.6)        <<<---- met
3    * vfio VGA support very likely needs to be enabled in the host kernel <<<---- met (?) i've CONFIG_VFIO_PCI_VGA=y
4    * The VM firmware must support specific fw_cfg enablers for IGD <<<---- What does it mean?
5    * The VM machine type must support a PCI host bridge at 00.0 (standard)
6    * The VM machine type must provide or allow to be created a special <<<---- What does it mean?
      ISA/LPC bridge device (vfio-pci-igd-lpc-bridge) on the root bus at
      PCI address 1f.0.
7    * The IGD device must have a VGA ROM, either provided via the romfile   <<<--- I don't know!
      option or loaded automatically through vfio (standard).  rombar=0
      will disable legacy mode support.
8    * Hotplug of the IGD device is not supported. <<<--- don't care
9 * The IGD device must be a SandyBridge or newer model device.<<<--- met



They say that igd passthrough is possible, and in particular i can see the very same parameter:

-device vfio-pci,host=00:02.0,id=hostdev0,bus=pci.0,addr=0x2

...is used when my Virtual Machine starts.

Through windows device manager i can say that the intel gpu is recognized, but it says it is not connected to any monitor.

My VM xml follows:

I also tried to install vnc on the VM, but as i try to connect to it, i've the same, a black window.



-EDIT-
Just tried with an arch installation (virtualized) booted via network, the same happens, but this time i can inspect the kernel log.
