    VM hosted SMB/CIFS storage cause ISO/template download corruption

    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...

    Kernel Crash in amdgpu driver when using MST

    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...

    Attach Brio USB Webcam to Linux VM

    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...

    VM hosted SMB/CIFS storage cause ISO/template download corruption

    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...

    VM hosted SMB/CIFS storage cause ISO/template download corruption

    Hello, I seem to be experiencing the same issue. Did you ever get to the bottom of this?

    Can I use one of two GPUs for passthrough and the other for VirGL?

    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...

    Can I use one of two GPUs for passthrough and the other for VirGL?

    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...

    Attach Brio USB Webcam to Linux VM

    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...

    VirtIO-GPU resolutions

    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...

    VirtIO-GPU resolutions

    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...

    Proxmox VE 7.3 released!

    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...

    Kernel 5.15.64 breaks my VMs

    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...

    Kernel 5.15.64 breaks my VMs

    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...
