The Linux kernel is a Unix-like operating system kernel. Released under the GNU General Public License version 2 (GPLv2) and developed by contributors worldwide, Linux is one of the most prominent examples of free software.
Proxmox VE 4.x
The current stable 4.x release uses latest Ubuntu based kernel, which will be regularly updated. The first stable 4.0 release is based on 4.2 Linux kernel. Since Proxmox VE 4.2 it is based on the 4.4 LTS Linux Kernel (using the Ubuntu 16.04 LTS Xenial Kernel as a base).
