Well, here's another experiment that might surprise you. I used both wget and curl to download the file just now from command line. Both were ran on host D and wrote remotely to the samba share mounted from VMhNAS. They both worked:
root@pve:~# curl -o...
Hello,
I have a Dell UltraSharp U4025QW monitor which has a feature that causes the kernel to crash: the iMST (internal Multi-stream Transport).
This iMST allows you to use the "daisy chain" DisplayPort feature and connect two separate monitors to the same port. In this particular model, there...
I just want to update this thread in order to report that the BRIO is now working just fine. Turns out I was using a very slow 480Mbps A-to-B cable so the hub to which the BRIO was connected was communicating very slowly with the Proxmox host. Now that I have a 10Gbps cable between the hub and...
Here is my situation:
I run proxmox on two machines, let's call them "H" and "D", where H is a "home server" and D is a "desktop with multi-seat".
- H runs a TrueNAS VM, let's call this "VMhNAS".
- D runs my Linux desktop VM (with GPU passthrough) as well as a Windows desktop VM (again with...
I have made some progress:
Running modbprobe amdgpu got this to work. After loading the driver there is now a /dev/dri directory and I am now able to start VMs with VirGL as the display.
The reason the driver was not loaded was that I had blacklisted amdgpu.
I have removed the blacklisting...
Hello,
I have two Radeon GPUs on my system: one 6700XT and one 6800. I have been using both with passthrough for a dual-seat configuration.
I now want to be able to use VirGL with one of the two. As I understand it, in order to do this the host must load the amdgpu drivers.
I have tried...
Hello,
I use Proxmox to run my main desktop. I run EndeavourOS (Arch-based) Linux on my main VM which has an RX6800 via PCI passthrough. It also has a USB mouse and keyboard that are attached to the VM.
Recently I got a Logitech Brio with USB signature 046d:085e and I cannot get it to work...
I have managed to solve this problem. The solution depends on whether you are using X11 or Wayland.
I use Wayland so the solution in my case was to add the following kernel parameter:
video=Virtual-1:2560x1440@60
After rebooting I was able to select my desired mode.
Source of fix: Dave...
Hello,
I run an Arch Linux VM using a VirtIO-GPU adapter. I connect to it mostly through RDP (I use Gnome's screen sharing) but also with the windows virt-viewer client. My problem is that I have a 27" monitor at 21:9 ratio and I want to run it at 2560x1440 resolution, yet that is not...
EDIT: adding the initcall_blacklist=sysfb_init kernel parameter fixed things for me! Everything now works as before. I did not have to uncheck the "All Functions" box like others have reported. The give-away if you have two VMs like me is that the one that has the issue will be the one logging...
Hi,
I just confirmed the work-around I hypothesized in my post: addint the blacklist configuration, together with the vfio options and the kernel parameters to not log on boot allows me to use 5.15.64.
I suspect that the AMD driver has a bug in its "release GPU" code that was introduced some...
Hello all,
I updated from 5.15.53-1-pve to 5.15.64-1-pve and my VMs have stopped working. When starting they UI simply prints an error that "Error: unable to read tail (got 0 bytes)". In /var/log/daemon.log I see:
Nov 14 21:30:25 pve pve-guests[7004]: start VM 101...
Thank you! I followed your instructions about unblacklisting the amdgpu module and removing all the kernel parameters and it works just fine!
I see the following in the kernel log when I start the VMs:
Jul 10 23:08:34 pve kernel: Linux version 5.15.39-1-pve (build@proxmox) (gcc (Debian...
Hi all,
I just located this thread after upgrading and running into GPU passthrough issues. My host is a 5950X with two GPUs: a 6700XT and a 6800. These are both passed through to VMs and I've been happily running with 5.13 kernel for a while, but after receiving 5.15 one of the two stopped...
After exhausting all options I looked at different 6000 series cards and ended up replacing the Aorus 6700 XT: there is simply something worng with that particular card.
I am now using:
MSI Radeon RX 6700 XT Mech 2X 12GB
Asrock Radeon RX 6800 Challenger Pro 16GB
Both of them work without...
Also note that if I suspend/resume the host, the issue is resolved and I can then successfully restart the VM and use the 6700XT in the VM.
Here is the command I use:
#!/bin/bash
N=4
echo "1" | tee -a /sys/bus/pci/devices/0000\:0b\:00.0/remove
echo "1" | tee -a...
I should note that:
The 6700XT is passed through with the ROM
hostpci0: 0000:0b:00,pcie=1,x-vga=1,romfile=Gigabyte.RX6700XT.12288.210318.rom
If I try the same with the RX550 (which uses the vendor-reset) everything works
