Kernel Management
|
|
=================
|
|
|
|
Warewulf nodes require a Linux kernel to boot. As of Warewulf v4.6, the kernel
|
|
you wish to use must be present in the relevant image. Warewulf locates and
|
|
provisions the kernel automatically for any node configured to use that
|
|
image.
|
|
|
|
You can see what kernels are available in imported images by using the
|
|
``wwctl image kernels`` command:
|
|
|
|
.. code-block:: console
|
|
|
|
# wwctl image kernels
|
|

Kernel Version
|
|
==============
|
|
|
|
If an image includes multiple kernels, the desired kernel may be selected by
|
|
specifying the desired version or an explicit path.
|
|
|
|
.. code-block:: console
|
|
|
|
# wwctl node set n1 --kernelversion=4.18.0-372.13.1
|
|
# wwctl node set n1 --kernelversion=/boot/vmlinuz-4.18.0-372.13.1.el8_6.x86_64
