    [SOLVED] 'pvecm qdevice setup' fails

    I'm in the same boat as FleetwoodMac here. Tried The Chain of solutions in this thread and others, I guess this project will be in my Dreams for now. I'm Never Going Back Again until I can find a new solution to try, I think I've tried what I found Everywhere. If anyone has any Second Hand...

    VLANs Above ~100 not working

    Hey all, have a weird issue I'm trying to solve. I have a switch that is trunking several VLANs to Proxmox, where only some are working. It seems that any VLAN above 100 isn't properly being seen by the VM. 100 works, but 255 or 200 do not. For example, I have a VLAN of 255 which I could...

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    It is a little bit of a hack, but this post solved my issues. I haven't seen any other methods that worked for me, seems to be a little bit of a dead end for now.

    GPU Passthrough Issues on kernel 5.15

    Yeah, I believe I've seen pretty much every post on this particular issue. I believe that we are the three posters who have talked the most about the process of getting GPUs passed through on the 5.15, with varying degrees of success. I wish I had a better understanding of the concepts and...

    GPU Passthrough Issues on kernel 5.15

    Sorry for the delay; I didn't have as much time to test this at work as I usually do. I am also glad for the sanity check around the GRUB lines being enough to prevent the memory from being occupied. I also again appreciate the help in diagnosing this, I hope this is as good of a brain teaser...

    GPU Passthrough Issues on kernel 5.15

    Of course, thank you for taking the time to help me dive into this. My kern.log shows this Apr 29 05:54:33 prox kernel: [ 126.700860] vfio-pci 0000:03:00.0: BAR 0: can't reserve [mem 0x33fe0000000-0x33fefffffff 64bit pref] Apr 29 05:54:33 prox kernel: [ 126.700877] vfio-pci 0000:03:00.0...

    GPU Passthrough Issues on kernel 5.15

    I believe I should be completely up to date, I'm trying with the Linux 5.15.30-2-pve #1 SMP PVE 5.15.30-3 (Fri, 22 Apr 2022 18:08:27 +0200) as well as pve-manager/7.1-12/b3c09de3 and my GRUB line looks like this GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt video=simplefb:off...

    GPU Passthrough Issues on kernel 5.15

    Thank you! Embarrassingly I had the correct nofb nomodeset video=vesafb:off video-efifb:off in my GRUB_CMDLINE_LINUX_DEFAULT, but in my laziness I posted the line from the tutorial I used, where it was incorrect. I completely forgot about the day that it took me to find the correction before...

    GPU Passthrough Issues on kernel 5.15

    Hey all, I have a Proxmox server running on kernel 5.13.19-4 where I have my GPU passthrough working perfectly. I am interested in getting ahead of the release of the 5.15 kernel, and I have opted in and gotten everything installed. However, on this newer 5.15 kernel I have only ever received...

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    I'm still not having any luck with GPU passthrough, could anyone who has it working offer their GRUB_CMDLINE_LINUX_DEFAULT line? I believe I have tried every combination I can think of, but I am sure I am missing or mis-thinking something. Thanks!

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    I tried 5.15.30, and unfortunately for me I still receive the endless "Cannot reserve BAR memory," so it appears to still be broken on my end. I have tried the video=simplefb:off in additional or as a replacement for the older fb code in my grub_cmdline_linux_default and it doesn't seem to...

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    Has anyone had any luck with PCIe passthrough in the 5.15 kernel, specifically passing through an Nvidia GPU? I am still on the 5.13.19 kernel, but am interested in returning back to the 5.15 kernel. My last attempts resulted in my LSI card (flashed into IT mode) and/or the Nvidia GPU...

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    I've tried adding that, both in conjunction with the vesafb and efifb stuff and without; neither seemed to make a difference to the passthrough problem.

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    I've tried 5.15 a couple of times since 5.13 broke my GPU passthrough. While I am able to get my LSI card passed through successfully, my GPU is never passed through, as the VM hangs on the BAR kernel message. I attempted again tonight with the updated 5.15 kernel as associated updates, but am...

    Latest Update 5.13.19-4-pve broke my QEMU PCIe Sharing. Works with 5.13.19-3

    You can either select it in the GRUB screen while Proxmox boots, or you can follow this post if you want to do it without a screen.

    Opt-in Linux Kernel 5.15 for Proxmox VE 7.x available

    I am having BAR Reservation issues with 5.15-17-1 that I wasn't having on 5.13-19-3 (but am having on 5.13-19-4). Has anyone else seen this? I see some reports of GPU and LSI passthrough working in 5.15, and am wondering if there is anything else I can try.

    Latest Update 5.13.19-4-pve broke my QEMU PCIe Sharing. Works with 5.13.19-3

    Can also confirm the pve-kernel update broke my PCIe passthrough. I've moved to the 5.15 kernel since I don't have the ability to attach a monitor and use the grub screen easily. 5.15 is working slightly better; my LSI card works but my GPU doesn't. Edit - Reverting back to 5.13.19-3 fixed...

    Issue with GPU passed through to Ubuntu

    Hey all, After much time and stress I am have (I think) properly configured my 1650 Super GPU passthrough in Proxmox 6.3-2 following several different guides. My ultimate goal is to use it to transcode in an Ubuntu VM running a Plex Docker, which I have seen other people do successfully. I...
