Hi Thanks for coming back to me on this, much appreciated. The ROM BIOS i915ovmf.rom did the trick in the end for me. As soon as I add that into the VM config, the monitor came to life straight away. Spent hours trying to solve this one. How did you come by the BIOS? Is this published somewhere or did you manage to dump it. I centrally tried to dump it via various methods but never managed to successfully grab it. Also note that I had:- PCIe ACS override: Disabled VFIO allow unsafe interrupts: No syslinux config video=efifb:off Cheers for the great support regards Al

I am trying to passthrough a single GPU to a Windows 10 VM. Hardware details are as follows:- HP 290 G2 MT 16gb RAM Intel i5-8500 CPU BIOS Version AMI F40 21/11/2019 Intel UHD Graphics 630 (integrated into CPU) also this is the only GPU After a lot of tinkerly around a managed to get the VM to recognise the GPU when using a RDP connection (before I was get error 43 in device manager for the UHD 630), however I always end up with a black screen on the undraid’s monitor after starting the VM. I have also tried to play around with the PCIe ACS override setting (Downstream, multi function or both) and tried the combinations with VFIO allow unsafe interrupts set to Yes. Also tried it with “Permit UEFI boot mode” enabled and Disabled. IOMMU Groups can be seen in the attachment XML Config for the VM is as follows:- XML Config for the VM is as follows <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm'> <name>Windows 10 bbb</name> <uuid>620dd81f-3632-636c-488d-75b34ef2beef</uuid> <metadata> <vmtemplate xmlns="unraid" name="Windows 10" icon="windows.png" os="windows10"/> </metadata> <memory unit='KiB'>5767168</memory> <currentMemory unit='KiB'>5767168</currentMemory> <memoryBacking> <nosharepages/> </memoryBacking> <vcpu placement='static'>2</vcpu> <cputune> <vcpupin vcpu='0' cpuset='0'/> <vcpupin vcpu='1' cpuset='1'/> </cputune> <os> <type arch='x86_64' machine='pc-i440fx-7.1'>hvm</type> <loader readonly='yes' type='pflash'>/usr/share/qemu/ovmf-x64/OVMF_CODE-pure-efi.fd</loader> <nvram>/etc/libvirt/qemu/nvram/620dd81f-3632-636c-488d-75b34ef2beef_VARS-pure-efi.fd</nvram> </os> <features> <acpi/> <apic/> <hyperv mode='custom'> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vendor_id state='on' value='none'/> </hyperv> </features> <cpu mode='host-passthrough' check='none' migratable='on'> <topology sockets='1' dies='1' cores='2' threads='1'/> <cache mode='passthrough'/> </cpu> <clock offset='localtime'> <timer name='hypervclock' present='yes'/> <timer name='hpet' present='no'/> </clock> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/local/sbin/qemu</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/user/domains/Test Win 10/vdisk1.img'/> <target dev='hdc' bus='virtio'/> <boot order='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </disk> <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <source file='/mnt/user/isos/virtio-win-0.1.221-1.iso'/> <target dev='hdb' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='1'/> </disk> <controller type='pci' index='0' model='pci-root'/> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </controller> <controller type='usb' index='0' model='ich9-ehci1'> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x7'/> </controller> <controller type='usb' index='0' model='ich9-uhci1'> <master startport='0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0' multifunction='on'/> </controller> <controller type='usb' index='0' model='ich9-uhci2'> <master startport='2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x1'/> </controller> <controller type='usb' index='0' model='ich9-uhci3'> <master startport='4'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x2'/> </controller> <interface type='bridge'> <mac address='52:54:00:87:79:73'/> <source bridge='br0'/> <model type='virtio-net'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target type='isa-serial' port='0'> <model name='isa-serial'/> </target> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <channel type='unix'> <target type='virtio' name='org.qemu.guest_agent.0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> <input type='tablet' bus='usb'> <address type='usb' bus='0' port='1'/> </input> <input type='mouse' bus='ps2'/> <input type='keyboard' bus='ps2'/> <audio id='1' type='none'/> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </source> <rom file='/mnt/user/domains/Test Win 10/intelgraphis.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x00' slot='0x1f' function='0x3'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source startupPolicy='optional'> <vendor id='0x046d'/> <product id='0xc548'/> </source> <address type='usb' bus='0' port='2'/> </hostdev> <hostdev mode='subsystem' type='usb' managed='no'> <source startupPolicy='optional'> <vendor id='0x09eb'/> <product id='0x0131'/> </source> <address type='usb' bus='0' port='3'/> </hostdev> <memballoon model='none'/> </devices> </domain> LOG file from VM can be seen in the attachment Additionally I tried to download a ROM file for the GPU however I was not able to do this, or even find one on the Internet for this GPU. Tried to download the vbios from GPU-z, Dump vBios Script in unraid, and Space Invador’s method from a putty session:- cd /sys/bus/pci/devices/0000:00:02.0 echo 1 > rom cat rom > /mnt/user/domains/Test Win 10/intelgraphis.dump echo 0 > rom At this stage I am a little lost and even wonder if what I am trying to achieve is even possible with this hardware? Any help or pointers on what I can try next would be greatly appreciated? Many thanks Al
