Introduction
Proxmox publishes three kernel branches, each one with minor feature differences. Currently, the 2.6.24 is the default and recommended branch - included from Proxmox VE 0.9 beta till Proxmox 1.4 (the current stable).
A Proxmox VE cluster master can manage a mixed kernel setup. For example, you can run two nodes with 2.6.18 and two nodes with 2.6.32. Depending on the features, some migrations are only possible between identical kernels.
Kernel 2.6.18
- Stable OpenVZ
- KVM
How to install 2.6.18
apt-get update apt-get install proxmox-ve-2.6.18
To make sure that you boot into the new kernel, check /boot/grub/menu.lst. Now reboot and check if the system is running the right kernel.
Kernel 2.6.24
- OpenVZ
- KVM
How to install 2.6.24
apt-get update apt-get install proxmox-ve-2.6.24
To make sure that you boot into the new kernel, check /boot/grub/menu.lst. Now reboot and check if the system is running the right kernel.
Kernel 2.6.32
- Latest KVM with KSM (shares identical memory pages, especially useful when running multiple guests from the same or similar base operating system image. Because memory is shared, the combined memory usage of the guests is reduced)
How to install 2.6.32
apt-get update apt-get install proxmox-ve-2.6.32
To make sure that you boot into the new kernel, check /boot/grub/menu.lst. Now reboot and check if the system is running the right kernel.
