Hello, I updated my PVE node, and after rebooting, I can't boot. Booting no longer works. I tried rescue mode, but I get to root@proxmox:/# on the USB drive; I'm limited. On usb key rescue : root@proxmox:/# view /boot/ System.map-6.14.8-2-pve config-6.14.8-2-pve vmlinuz-6.14.8-2-pve...

Hello, I would like to pin VM vCPU threads to physical CPU threads. I mean when you defice CPU affinities in VM / Hardware / Processor / CPU affinitiy: n-m. E.g If I set CPU affinity to 2,5,9-11, I would like to have option that instead of current functionality that VM vCPU threads uses above...

Hi - my Proxmox installation was running OK. A while back I did some updates which included a kernel update, the system updated to proxmox-kernel-6.8 version 6.8.12-13. A while after (around 2-3 days) I noticed that the system (an Intel NUC) was down — power light on but system unreachable. The...

Hi ! I'm working on a PVE setup for 2 weeks now and one of the servers is a SimplyNUC server running PVE 8.4.11. Yesterday suddenly I couldn't reach it anymore and had to hard reboot the machine. I then checked the logfiles and saw the following: Aug 20 18:27:59 site1-snuc pvedaemon[1518]...

Hi, I am fairly new to Linux and definitely a noob to Proxmox so I was hoping I could get some answers here. I wanted to Run HyperHDR an lxc and I found this helpful script which will do that for me. The problem that the default Linux Kernel has a specific feature turned off by default...

Hello all, I’m trying to get the newer LTTng 2.13.18 DKMS modules working on my Proxmox VE 8 host (kernel 6.8.12-9-pve), but every attempt trips the pve-apt-hook and wants to remove the proxmox-ve meta-package. Below is what I’ve done so far and the exact errors I see. - Host: Proxmox VE 8.x...

Hi Experts I'm installing Proxmox on top of Debian for disk encryption purposes. Everything seems to work fine for Proxmox but I can't get secure boot to be working. Secure boot worked for a normal Proxmox ISO installation (not with Debian). I got this while booting up: Loading Linux...

Hello all, I want to change some kernel parameters, to increase the performance of my PVEs. I want to set the processor.max_cstate=1 and intel_idle.max_cstate=0 parameters. So, I updated /etc/default/grub, added the options to the GRUB_CMDLINE_LINUX variable, and ran both update-grub and...

Hello, I do have two identical host, same hardware everywhere. One of them keep crashing at random times. I look on this forums, found lots of similar post but, I don't want to try random things and break the system and make things even more bad. When it crashes, it won't reboot by itself...

Hey guys, I'm trying to build a custom kernel but whatever I do I am unable to edit the config of the kernel, it always reverts to the default. git clone git://git.proxmox.com/git/pve-kernel.git cd pve-kernel nano Makefile # I edit this line: EXTRAVERSION=-$(KREL)-pve-custom make...

``` git clone https://git.proxmox.com/git/pve-kernel.git make submodule ``` Then I added `-e CONFIG_LTO_CLANG` and `-e CONFIG_LTO_CLANG_FULL` into `pve-kernel/debian/rules` 's `PMX_CONFIG_OPTS` then `make LLVM=1`, but errors came out:

I'm looking at the instructions for installing Proxmox on top of an existing Debian 12 system. In section 3.2 it mentions installing a custom Proxmox kernel, with this explanation: The example given is puzzling in that the stock Debian kernel has had apparmor enabled for eleven years. What...

Hello, I'm currently setting up a testing environment based on a 2 nodes Proxmox cluster. The 2 nodes are absolutely identical machines (micro-PC). I've followed the exact same procedure to install both nodes, booting from the proxmox-ve_8.3-1.iso. Both installations went off without a hitch...

I have just built a new server, and installed v8 straight away. Apart from a minor issue with NVMe which seems to be a BIOS related (they appear or not randomly after the POST) I opted to stay safe and installed everything on a single SSD in ext4. Call me old school, I'm fine with that :) So I...
