Hello, everyone
I'd like to share my experience with QEMU/Libvirt and sharing Intel GPU with guest VM.
And ask community for advice
My host is HP Elitedesk 800 G3 - Intel i3-7100 with HD630
OS - Linux archlinux 6.11.6-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 01 Nov 2024 03:30:41 +0000 x86_64 GNU/Linux
I can pass through iGPU to a guest OS everything is fine except that no output from DP.
When adding this section along with rom file output appears (after OS boots up)
<qemu:override>
<qemu:device alias='hostdev0'>
<qemu:frontend>
<qemu:property name='x-igd-opregion' type='bool' value='true'/>
</qemu:frontend>
</qemu:device>
</qemu:override>
However, I still have 2 problems:
1. Occasional DMAR errors in dmesg
2. Unpredictable hang of host as well as guest with network connection lost. This might take up to several hours, but always happens.

Despite providing UEFI vbios rom file, error Invalid PCI ROM header persists
Output and display works fine, except there is nothing before OS boots
vfio-pci 0000:00:02.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffffrom-parser reports that this rom is UEFI
Valid ROM signature found @0h, PCIR offset 1ch
PCIR: type 3 (EFI), vendor: 1f96, device: 0778, class: 000000
PCIR: revision 3, vendor revision: 0
EFI: Signature Valid, Subsystem: Boot, Machine: X64

Continue answering my initial post and adding details.
Freezes continues even with NVidia GPU (I have old GT 710) and Arch Linux as a guest. I thought, these hangs might be due to iGPU and absence of VBIOS rom file for my MB. However, it turned out that even with dedicated GPU the problem persists.
Yesterday, while reading up forms and post on the Internet, I added Intel microcode package to the guest OS (it's already been installed on the host). The result is 10+ hours steady work. It might be the root cause for the problem, but let's wait and see.
In the same time, Windows guests are working fine without any freezes with iGPU

I'd like to ask experienced users - how to extract IntelGopDriver.efi from MB firmware. UEFITools can parse this firmware, can find MBR video bios and extract it as well as VBT table. But I can't find IntelGopDriver. It might be hidden under GUID.
And final question - how to combine this 2 file to produce a valid uefi-style VBIOS

Random hangs and panics. I believe it related to rtl8169 driver
