Hi There, I currently have a 2-node PVE 6 cluster (and 3rd node QDevice), with the 2 nodes operating headless with PVE installed as ZFS on EFI (systemd-boot). If I want to test the new PVE Linux 5.3 kernel on one of the nodes, I understand that I just need to do: apt update && apt install...

Hi, I'm trying to patch a upstream kernel driver (ath.ko). Doing so should be fairly easy even though it seems a bit clumsy. It requires to install the "linux-sources" package from APT, extract the kernel source file that gets downloaded with it, patch it, compile the module and install the...

Hi guys, I need to create some CT with MPTCP kernel installed, how can I create custom kernel to add it to Proxmox VE and run the CT with MPTCP kernel?

Where is the Official Proxmox documentation that addresses the best practice for removing old kernels? So far, none of the posts I've read (in the forum) satisfy me regarding this topic. Partly, this dissatisfaction is due to the fact that different posters are suggesting different practices...

Hello! Occasionally the pve-kernel gets updated. I am using DKMS to compile the drivers for a device when the kernel gets updated. The catch lies in the fact that in order to compile those drivers, kernel headers are necessary and on update are missing. This results in the system becoming...

Using Proxmox 5.4.6. I have installed pve-headers package but whenever I try to install something that requires it (wireguard) I'm getting the following error: Error! Your kernel headers for kernel 4.15.18-14-pve cannot be found. Please install the linux-headers-4.15.18-14-pve package, or use...

Hello together, I have some strange issue with PVE 5.3 and 5.4. I can install Proxmox without any issue. But the PVE Kernel will not boot. After GRUB Loader I can see "normal" boot messages and after that (the moment where normally the prompt appears) the screen stays black and nothing...

I looked at the roadmap and I'm not seeing release notes for the patches and updates released periodically. Is there a place that I can read the release notes for patches as they come through to track changes or be aware of gotchas? Example today I see that the following updates are available...

Hi, I've started using Proxmox about 6 months ago and have been loving it. Last night, I found that my Plex container was not responding. All other VMs and containers were fine (only 2 others on the machine). I was able to login via SSH and found the following in the journal: Jan 13 01:24:13...

Recently I installed kernel 4.19 from Ubuntu and then I recompile zfs - everything without any proxmox patches . So far everything is running smooth but I'm wandering what I lost using ubuntu kernel instead of proxmox. What are the disadvantages of such a solution? The reason why I did it is...

Hi, Is there any documentation how can I compile my own kernel and apply proxmox patches? I was trying to use one from proxmox github but this only can be used for 4.15 not for the latest... Best regards, Morbious

Why Proxmox does not do any workaround this kernel cleaning process? We had not touched this, yet it seems our disks are getting clogged and the upgrade process is prolonged only due to so many kernel checks and yeah, what a day. So how does one, "safely" clean up OLD Kernels, and why they are...
