I’m trying to set up a fresh install of Proxmox 5.2 on Gemini Lake and I would like to configure a VM with IGD (graphics) passthrough for Ubuntu 18
Computer-based on ASRock J4105-ITX asrock.com/mb/Intel/J4105-ITX/
A standard install is working properly and now I would like to use HDMI output for a VM with Ubuntu 18.
I have read all this information:
- https://pve.proxmox.com/wiki/Pci_passthrough
- https://forum.proxmox.com/threads/guide-intel-intergrated-graphic-passthrough.30451/
- https://redhat.com/archives/vfio-users/2017-April/msg00032.html
- https://forum.proxmox.com/threads/proxmox-5-0-kaby-lake-and-igd-graphics-passthrough-for-windows-10.36165/
My setup is like this:
- Fresh install Proxmox 5.2
Grub:
vim /etc/default/grubChange the
GRUB_CMDLINE_LINUX_DEFAULTline to
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on video=efifb=off,vesafb=off"`Save and quit
update-grubBlacklist module:
vim /etc/modprobe.d/pve-blacklist.confAdd these lines:
blacklist snd_hda_intel blacklist snd_hda_codec_hdmi blacklist i915Save and quit
VFIO:
vim /etc/modulesAdd these lines:
vfio vfio_iommu_type1 vfio_pci vfio_virqfd save and quitVga adapter:
lspci -n -s 00:02 lspci command display 00:02.0 0300: 8086:3185 (rev 03) vim /etc/modprobe.d/vfio.confAdd this line:
options vfio-pci ids=8086:3185Save and quit
update-initramfs -uVM:
Create a VM (id = 100) with an Ubuntu 18 iso as the primary boot
Change the setup for the VM:
vim /etc/pve/qemu-server/100.confAdd these lines:
machine: pc-i440fx-2.2 args: -device vfio-pci,host=00:02.0,addr=0x02 vga: noneSave and quit
Reboot the server
Start VM 100
Video output is initialised (clear screen) just after the VM 100 is started but the screen remains black. Start task log is:
no efidisk configured! Using temporary efivars disk.
kvm: -device vfio-pci,host=00:02.0,addr=0x02,x-igd-gms=1,x-igd-opregion=on: IGD device 0000:00:02.0 has no ROM, legacy mode disabled
TASK OK
I try to install Ubuntu before change config, but it doesn't help.
What should I do now?
