Kernels

The Clear Linux* OS provides the following Linux kernels with a respective bundle. This document describes the specific use cases these bundles serve and provides links to their source code.

Bare metal only

Kernel native

The kernel-native bundle focuses on the bare metal platforms. It is optimized for fast booting and performs best on the Intel® Architecture Processors described on the supported hardware list. The optimization patches are found in our Linux GitHub* repo.

Also compatible with VMs

Kernel LTS

The kernel-lts bundle focuses on the bare metal platforms but uses the latest LTS Linux kernel. It is optimized for fast booting and performs best on the Intel® Architecture Processors described on the supported hardware list. Additionally, this kernel includes the VirtualBox* kernel modules, see our instructions on using Virtualbox for more information. The optimization patches are found in our Linux-LTS GitHub repo.

VM only

Kernel KVM

The kernel-kvm bundle focuses on the Linux KVM. It is optimized for fast booting and performs best on Virtual Machines running on the Intel® Architecture Processors described on the supported hardware list. Use this kernel when running Clear Linux OS as the guest OS on top of qemu/kvm. Use this kernel with cloud orchestrators using qemu/kvm internally as their hypervisor . This kernel can be used as a standalone Clear Linux OS VM, see our instructions on using KVM for more information. The optimization patches are found in our Linux-KVM GitHub repo.

Kernel Hyper-V*

The kernel-hyperv bundle focuses on running Linux on Microsoft* Hyper-V. It is optimized for fast booting and performs best on Virtual Machines running on the Intel® Architecture Processors described on the supported hardware list. Use this kernel when running Clear Linux OS as the guest OS of Cloud Instances in projects such as Microsoft Azure*. This kernel can be used in a standalone Clear Linux OS VM, see our instructions on using Hyper-V for more information. The optimization patches are found in our Linux-HyperV GitHub repo.
