You can Switch on Boot via Grub back to the Normal PVE Kernel

Ok but I dont understand why should I install custom kernel if i switch back to the normal.
Which kernel did you use before custom one

 

[hchristo]

i install the XanMod Kernel for Testing and for More Performance. I´ve Install also XanMod on all my Linux (Debian) VM´s.
I Install my Proxmox manualy too, Based i install Debian 12 without SWAP Partition and after that Proxmox.

Ok but how to install this kernel

From My Wiki:

Important note

I accept no liability for damage to your system!

These instructions have been adapted to my system, the test with other systems has never taken place.
It is recommended that only experienced administrators implement these instructions.
Applying the instructions to your own system is your own responsibility!

Now a new kernel. I recommend the XanMod kernel, which can be installed as follows:

0. Optional - installation of any required packages:
apt install curl ca-certificates apt-transport-https sudo gnupg gnupg2 net-tools -y

1. check which kernel is suitable for me. This is important to check which kernel is suitable for the system.
wget -O check_x86-64_psabi.sh https://dl.xanmod.org/check_x86-64_psabi.sh && chmod 755 check_x86-64_psabi.sh && ./check_x86-64_psabi.sh
Output: CPU supports x86-64-vX where the underlining X stands for the version number. Example output: CPU supports x86-64-v3

2. register the PGP key:
wget -qO - https://dl.xanmod.org/archive.key | sudo gpg --dearmor -o /usr/share/keyrings/xanmod-archive-keyring.gpg

3. import the Sources List:
echo 'deb [signed-by=/usr/share/keyrings/xanmod-archive-keyring.gpg] http://deb.xanmod.org releases main' | sudo tee /etc/apt/sources.list.d/xanmod-release.list

4. update and install the kernel, following the kernel support in step 1:
sudo apt update && sudo apt install linux-xanmod-lts-x64v3 -y
