HI Alex,
I am trying for legacy mode, which means that video from the VM will be out the HDMI port of the motherboard and the VM shall have exclusive use of the GPU.
I have set ignore_msrs=1 but don' have videowhen using OVMF and UEFI only.
The problem that I have is that to do a clean install of windows I need to have video enabled (which isn't possible unless you add a qxl device (ie add -device qxl-vga to the command line).
How do I install windows without having any video enabled? OVMF doesn't recognise the UEFI device - do I need UEFI bios for that? I think that I am missing some key point.
Cheers
Chris

There is nothing display until the i915 driver is loaded on the guest which is expected. I have a couple of questions tho, as I cannot get windows 10 to boot:Do I need to specify the bios? I have tried getting the bios using the intel 01.org site but that bios is only in an older kerne and it is a VGA video bios. I am using pure UEFI.The windows install has the windows drivers working as I have taken the image from the same machine that I installed it on but it refuses to boot. I tried enabling the QXL video card on a different PCI slot (-vga wont do with qemu 2.8) and I got video out, but crashes when the IGD driver was loaded. How is it possible to debug this in windows, as nothing appears in the event log.http://git.qemu.org/?p=qemu.git;a=blob;f=docs/igd-assign.txtHaswell is only supported in legacy mode, which requires guest firmware support which is only present in SeaBIOS, not OVMF. Windows 10 should work fine, be sure to use the ignore_msrs module option for kvm if you get bsods. Thanks,Alex
