IGD Passthrough doesn't work after upgrade

[coyote]

Hello,

I used IGD Passthrough (https://forum.proxmox.com/threads/guide-intel-intergrated-graphic-passthrough.30451/) for a few weeks with Mint VM. After upgrade to Kernel 4.15.18-9 it doesn't work anymore.

Hope anyone can help me

Edit: How can i choose an older Kernel?

 

[dcsapak]

can you post your vm config ?

 

[coyote]

Sure.

VM Config:

agent: 1
args: -device vfio-pci,host=00:02.0,addr=0x02
bootdisk: scsi0
cores: 4
ide2: QNAP:iso/linuxmint-19-cinnamon-64bit-v2.iso,media=cdrom
machine: pc-i440fx-2.2
memory: 2048
name: test
net0: virtio=7A:27:43:CC:06:1F,bridge=vmbr0
numa: 0
ostype: l26
scsi0: QNAP:104/vm-104-disk-0.qcow2,size=15G
scsihw: virtio-scsi-pci
smbios1: uuid=2a330518-b5bd-47e9-b0b8-3c24ad43353b
sockets: 1
usb0: host=1-2.3
vga: none

 

[dcsapak]

args: -device vfio-pci,host=00:02.0,addr=0x02

i would replace that line with 'hostpci0: 00:02.0'

the address 0x02 gets used by the vga

vga: none

this has not worked since at least 4.0

if you want no vga for the vm use

'hostpci0: 00:02.0,x-vga=on'

this disables the qemu vga hardware

 

[coyote]

Ok, tried new config:

agent: 1
hostpci0: 00:02.0,x-vga=on
bootdisk: scsi0
cores: 4
ide2: QNAP:iso/linuxmint-19-cinnamon-64bit-v2.iso,media=cdrom
machine: pc-i440fx-2.2
memory: 2048
name: test
net0: virtio=7A:27:43:CC:06:1F,bridge=vmbr0
numa: 0
ostype: l26
scsi0: QNAP:104/vm-104-disk-0.qcow2,size=15G
scsihw: virtio-scsi-pci
smbios1: uuid=2a330518-b5bd-47e9-b0b8-3c24ad43353b
sockets: 1
usb0: host=1-2.3

VM boot without error in log, but apparently not correct. There's no picture on the HDMI Monitor and i can't reach VM over Teamviewer or Anydesk.

If i use this config:

agent: 1
bootdisk: scsi0
cores: 4
ide2: QNAP:iso/linuxmint-19-cinnamon-64bit-v2.iso,media=cdrom
memory: 2048
name: test
net0: virtio=7A:27:43:CC:06:1F,bridge=vmbr0
numa: 0
ostype: l26
scsi0: QNAP:104/vm-104-disk-0.qcow2,size=15G
scsihw: virtio-scsi-pci
smbios1: uuid=2a330518-b5bd-47e9-b0b8-3c24ad43353b
sockets: 1
usb0: host=1-2.3

it boots up fine and i can reach it over Teamviewer or Anydesk.

If i just use

hostpci0: 00:02.0

noVNC Console shows a black Picture and VM is not reachable over Teamviewer or Anydesk.



Another idea?

 

[dcsapak]

Another idea?

no basically what you wrote in the 'args' line does the same as 'hostpci'

you can of course try again with your 'args' line and a different pci slot...

maybe the reason why you do not see anything is that your guest expects the card on the '0x02' address where it was previously
could you try to install another os in another (similar configured) vm to test if that is the case?

 

[loomes]

I think this is not Kernel related. More qemu.
I have used this for my windows 10 VM: args: -device vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:00:02.0/b3dfe34f-0fdf-4321-8d03-42c4267ab5e1,rombar=0

After some Updates (proxmox) two weeks ago or so without a proxmox reboot (Kernel 4.15.18-7) i shutdown my win10 VM and they never come up again with the same error message like "PCI: slot 2 function 0 not available ..."

Maybe, your right. Same here, i did update for update without reboot proxmox. Yesterday i reboot and now VM doesn't work.


I did a few tests like dcsapak write:

New VM with "hostpci0: 00:02.0" -> there are a picture in Console (VM boot) and there is a signal on my Display but there are green stripes.



I tried "hostpci1: 00:02.0" same result.
I tried with "args:...." line, still no luck.

I updatet to the new 5.3 proxmox version and choose PCI device in Hardware Menu, with same result.
I don't no what's wrong. Maybe two weeks before it works fine with the guide in first post.

Ok i upgraded to v5.3:

Shutdown my Win10 VM.
Then i remove all my old manual added vgpus.

echo '1' > /sys/bus/pci/devices/0000:00:02.0/b3dfe34f-0fdf-4321-8d03-42c4267ab5e1/remove
echo '1' > /sys/bus/pci/devices/0000:00:02.0/b3dfe34f-0fdf-4321-8d03-42c4267ab5e2/remove
echo '1' > /sys/bus/pci/devices/0000:00:02.0/b3dfe34f-0fdf-4321-8d03-42c4267ab5e3/remove

And now i added the vgpu per new GUI Option.
Config file now:

cat /etc/pve/qemu-server/120.conf
agent: 1
args: -device intel-hda,id=sound5,bus=pci.0,addr=0x18 -device hda-micro,id=sound5-codec0,bus=sound5.0,cad=0 -device hda-duplex,id=sound5-codec1,bus=sound5.0,cad=1

boot: cdn
bootdisk: scsi0

cpu: host,flags=+pcid;+spec-ctrl
hostpci0: 00:02.0,mdev=i915-GVTg_V5_4,x-vga=1,romfile=undefined,rombar=0
keyboard: de
memory: 4096
name: win10
net0: virtio=66:6E:FC:77:C9:85,bridge=vmbr0
numa: 0
ostype: win10
scsi0: local-lvm:vm-120-disk-0,cache=writeback,discard=on,size=100G,ssd=1
scsihw: virtio-scsi-pci
smbios1: uuid=ddb19fd5-e307-4cc6-b378-8085bbc9428a
sockets: 1
tablet: 0
usb0: spice
vga: qxl

And the VM starts and running with the vgpu
The vGPU id would be generated automaticly from Proxmox itself now:

ll /sys/bus/pci/devices/0000\:00\:02.0/mdev_supported_types/i915-GVTg_V5_4/devices/
insgesamt 0
lrwxrwxrwx 1 root root 0 Dez  4 20:09 00000000-0000-0000-0000-000000000120 -> ../../../00000000-0000-0000-0000-000000000120

P.S. The Behavior is the same as before. When vgpu is in use only RDP is possible.
When i remove the x-vga=1 spice and novnc connections are possible but mouse cursor is invisible.

Edit2: Memory Balloning is now working when vgpu is active

 

[coyote]

GPU Passthrough to my Win10VM works. I choose PCI device over GUI in 5.3.
Second Picture is without Passthrough


Same in MintVM, Intel GPU is there, if i choose it in GUI.

My Problem is, it doesn't work on HDMI Output on my NUC. I have no Picture on my HDMI Monitor. It just works over noVNC Console


Edit: If i choose this config, i get the screen with the green stripes

 

[coyote]

Is it possible to rollback to an older proxmox version? I would like to test if this works with hdmi output.

 

[dcsapak]

hostpci0: 00:02.0,mdev=i915-GVTg_V5_4,x-vga=1,romfile=undefined,rombar=0

the 'undefined' thing look weird, what browser do you use?

also you could try to set the machine type to the older one with

qm set ID -machine pc-i440fx-2.11

to set it to 2.11 for example

also what kind of hardware is it ? (mainboard/cpu/etc.)

 

[coyote]

Sorry, that's the config from member "loomes" and his VM is working now.

This is my Hardware:

• Barebone Nano PC
• Intel Core i3-7100U mit 2x 2,4GHz / 3MB Cache (2 Cores / 4 Threads)
  
• 2x SODIMM DDR4 2133MHz Steckplätze für bis zu max 32GB Speicher
• Intel HD Graphics 620 mit HDMI 2.0, mini Displayport 1.2 via USB-C Anschluss

 

[dcsapak]

ok maybe you need the x-igd-opregion option for the gpu

get the command with

qm showcmd ID --pretty

and add ',x-igd-opregion=on' to the line with "-device 'vfio-pci'"

and start that

if this works, we can maybe include that in the config schema so that it can be set

 

[coyote]

Ok, that's output:

Should i use 106.conf file to add ',x-igd-opregion=on' into "args:..." line or into "hostpci0:....." line?

I get also this error on Passthrough NVIDIA GTX 1070:

yes we did not specify the port for the vga, (now we do) so you have to adapt that in the new version (for hostpci we use port 0x10 by default)

but in your case you should be able to do the passthrough through our 'hostpci' setting
(hostpci0: 1a:00.0,x-vga=on )

Should i use 106.conf file to add ',x-igd-opregion=on' into "args:..." line or into "hostpci0:....." line?

i meant to modify the output of showcmd and executing that directly in the shell

I tried this config:

Last working qemu-version was qemu-server: 5.0-38.
I've installed this version until the problem gets fixed:
Code:
apt install qemu-server=5.0-38
pveversion -v

Can't install "old" qemu-server.
Get this:

root@pve:~# apt install  qemu-server=5.0-38
