Proxmox Edge kernels

Custom Linux kernels for Proxmox VE 7.

Available Versions

1. Linux 6.0
2. Linux 5.19 [EOL]

Older builds are still available at the Releases page.

Installation

First, set up our Debian repository on your Proxmox installation:

1. Add the repository's GPG key:

   curl -1sLf 'https://dl.cloudsmith.io/public/pve-edge/kernel/gpg.8EC01CCF309B98E7.key' | gpg --dearmor -o /usr/share/keyrings/pve-edge-kernel.gpg

2. Set up the pve-edge-kernel repository:

   echo "deb [signed-by=/usr/share/keyrings/pve-edge-kernel.gpg] https://dl.cloudsmith.io/public/pve-edge/kernel/deb/debian bullseye main" > /etc/apt/sources.list.d/pve-edge-kernel.list

3. Install a kernel package:

   apt update
   apt install pve-kernel-6.0-edge

Package repository hosting is graciously provided by Cloudsmith. Cloudsmith is the only fully hosted, cloud-native, universal package management solution, that enables your organization to create, store and share packages in any format, to any place, with total confidence.

Manual

Alternatively, you may manually install the kernels. Select from the Releases page the kernel version you want to install and download the appropriate Debian package. Then, you can install the package as follows:

apt install ./pve-kernel-VERSION_amd64.deb

Building manually

You may also choose to manually build one of these kernels yourself.

Prerequisites

Make sure you have at least 10 GB of free space available and have the following packages installed:

apt install devscripts debhelper equivs git

Obtaining the source

Obtain the source code as follows:

git clone https://github.com/fabianishere/pve-edge-kernel
cd pve-edge-kernel

Then, select the branch of your likings (e.g. v6.0.x) and update the submodules:

git checkout v6.0.x
git submodule update --init --depth=1 --recursive linux
git submodule update --init --recursive

Building

First, generate the Debian control file for your kernel by running the following in your command prompt:

debian/rules debian/control

Before we build, make sure you have installed the build dependencies:

sudo mk-build-deps -i

Invoking the following command will build the kernel and its associated packages:

debuild -ePVE* --jobs=auto -b -uc -us

The Makefile provides several environmental variables to control:

1. PVE_KERNEL_CC
   The compiler to use for the kernel build.
2. PVE_KERNEL_CFLAGS
   The compilation options to use for the kernel build. Use this variable to specify the optimization level or micro architecture to build for.

Kernel options may be controlled from debian/config/config.pve. To build with additional patches, you may add them to the debian/patches/pve directory and update the series file accordingly.

Removal

Use apt to remove individual kernel packages from your system. If you want to remove all packages from a particular kernel release, use the following command:

apt remove pve-kernel-6.0*edge pve-headers-6.0*edge
