  1. DirtyPipe (CVE-2022-0847) fix for Proxmox VE

    Everything looks fine here too with the updated kernel, Windows VMs are running normally, and no more error logs. @t.lamprecht thanks a lot for your quick response to address the bug !
  2. DirtyPipe (CVE-2022-0847) fix for Proxmox VE

    Sorry for the late reply. In case you need, here is my config # qm config 105 agent: 0 bootdisk: ide0 cores: 4 cpu: host,flags=+hv-tlbflush ide0: local:105/vm-105-disk-0.raw,size=200G ide3: none,media=cdrom localtime: 1 memory: 16384 name: winsrv105 net0: virtio=XX:XX:XX:XX:XX:XX,bridge=vmbr1...
  3. DirtyPipe (CVE-2022-0847) fix for Proxmox VE

    I confirm the bug. In my case all CTs and Debian VMs start and work fine but Windows VMs seem to be stuck in a loop. I don't even get a console for those VM, however they appear as started in qm list. And syslog keep filling endless with errors like the one below Mar 08 01:09:45 ns3192824...
  4. [SoYouStart] rEFInd/Grub Boot Error (Upgrading Proxmox 6 to 7)

    @Obi_Yoann, @p1new &al HUUUUUGE thanks for your explanations. Copying the new grubx64.efi worked fine for me to fix the broken boot with "grub_is_lockdown" error after a 6 to 7 upgrade on OVH server.
  5. Quadro P400 Passthrough

    I don't have much ideas to help you, but are you sure you were able to follow the procedure in the link I gave you to extract the ROM ? This requires to first install the GPU as a secondary on the VM, meaning that you need a working primary GPU for that VM. Then, you should be able to boot...
  6. Quadro P400 Passthrough

    dmesg might help to understand what's going on, I'm not sure. Also, Did you try with the dumped rom before using GopUpdate ? GopUpd is necessary only if your original GPU rom doesn't have an EFI GOP (usually quite old models), in order to add one. That might not be the case of your Quadro, I...
  7. Inhibit All VM's from starting at boot for troubleshooting purposes... Possible???

    I believe the second option is more future-proof but both work fine. Maybe you could mark the thread as "solved". You just have to edit your first post and change the flag before the title to "solved"
  8. Quadro P400 Passthrough

    Hi ! I'm not familiar with Quadro GPU, but I was struggling with an old GT640 giving me the infamous error 43 until I managed to extract properly the ROM file from my GPU. Have a look at this thread, the given extraction method worked for me (then I had to add the GOP to the rom file using GOPUpd).
  9. Inhibit All VM's from starting at boot for troubleshooting purposes... Possible???

    And here is a much cleaner / proper solution (also to be tested), using pct/qm command # Disable autoboot for all CT for ct in $(pct list | awk '{print $1}' | grep -Eo '[0-9]{1,3}'); do pct set $ct --onboot 0; done # Disable autoboot for all VM for vm in $(qm list | awk '{print $1}' | grep...
  10. Inhibit All VM's from starting at boot for troubleshooting purposes... Possible???

    Hi, You can replace the value for the "onboot" param in all the conf files at once with sed. Here is an example. I didn't test it, so please use with care and try it carefully before using and/or backup your conf files... # Disable autoboot for all CT sed -i -e "s/^onboot: 1/onboot: 0/g"...
  11. [SOLVED] GPU passthrough working for 2 GPU but not for 1

    @Asano, thanks a lot for your tips ! It worked ! For all my previous attempts, I had extracted my "original" GPU rom with GPU-Z, and it seems that it wasn't working properly... I used your method to extract the rom, then I updated it with GOPUpdate and I was finally able to use my old GT640...
  12. [SOLVED] GPU passthrough working for 2 GPU but not for 1

    That sounds promising, thanks for the hint. I can’t give it a try right now but I will this weekend !
  13. [SOLVED] Is PCIe Passthrough supposed to work with Proxmox 7?

    Hi ! I've been able to passthrough a PCIe GTX1660 on a fresh install of Proxmox 7 with no problem, as well as many other devices : USB keyboard and mouse, a whole SATA HDD... My MB is a Gigabyte X570 I haven't tried on an upgraded Proxmox but I'd suspect some configuration changes, or device...
  14. [SOLVED] GPU passthrough working for 2 GPU but not for 1

    Hi ! I'm trying to set up a GPU passtrough to a Win10 VM. I've followed all instructions and procedures, and it's partially working, but I've got a weird case and no more clues... The host has 2 video cards : A GTX1660 on PCIe slot 1 A GT640 (Asus GT640-2GD3) on PCIe slot2 When I add the...
