[Question] SR-IOV, creating virtual/fake monitor so that the host can have a display inside the VM

Hello,

Something I've been wondering about, is it possible to create a fake/virtual monitor with the SR-IOV feature ?

Currently, when passing-through the VF devices inside a Windows guest, there's no display/monitors attached to them which makes it impossible to have an accelerated display (we are stuck using a remote display protocol currently from my research and understanding).

There's currently two approaches I think that could solve the problem:

- Modify the Intel GPU driver inside the Windows guest to have the possibility to create dummy video output so that https://looking-glass.io can be used ? (it means that Intel needs to modify the proprietary Windows driver)
- A virtual monitor could be created, so that we can display inside the linux host the Windows guest by modifying the i915's SR-IOV driver somehow ? (I could do that if it's possible, but I guess I'll need some guidance)

Sorry if it has been already answered, already asked or solved.

Thank you.
