Kernels
#######
The |CL-ATTR| 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® architectures
described on the :ref:`supported hardware list<system-requirements>`. The
optimization patches are found in our `Linux`_ GitHub\* repo.
.. _vm-kernels:
Also compatible with VMs
************************
Kernel LTS
The *kernel-lts* bundle focuses on the bare metal platforms but uses the
latest :abbr:`LTS (Long Term Support)` Linux kernel. It is optimized for
fast booting and performs best on the Intel® architectures described on the
:ref:`supported hardware list<system-requirements>`. Additionally, this
kernel includes the VirtualBox\* kernel modules, see our
:ref:`instructions on using Virtualbox<virtualbox-cl-installer>` 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
:abbr:`KVM (Kernel-based Virtual Machine)`. It is optimized for fast
booting and performs best on Virtual Machines running on the Intel®
architectures described on the
:ref:`supported hardware list<system-requirements>`. Use this kernel when
running |CL| 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 |CL| VM, see our
:ref:`instructions on using KVM<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® architectures described on the
:ref:`supported hardware list<system-requirements>`.
Use this kernel when running |CL| as the guest OS of **Cloud Instances** in
projects such as Microsoft `Azure`_\*. This kernel can be used in a
standalone |CL| VM, see our :ref:`instructions on using Hyper-V<hyper-v>`
for more information. The optimization patches are found in our
`Linux-HyperV`_ GitHub repo.
Kernel Hyper-V LTS
The *kernel-hyperv-lts* bundle focuses on running Linux on Microsoft
Hyper-V but uses the latest :abbr:`LTS (Long Term Support)` Linux kernel.
It is optimized for fast booting and performs best on Virtual
Machines running on the Intel® architectures described on the
:ref:`supported hardware list<system-requirements>`.
Use this kernel when running |CL| as the guest OS of **Cloud Instances** in
projects such as Microsoft `Azure`_. This kernel can be used in a
standalone |CL| VM, see our :ref:`instructions on using Hyper-V<hyper-v>`
for more information. The optimization patches are found in our
`Linux-HyperV-LTS`_ GitHub repo.
