Kernel Boot Options

MAAS is able to specify kernel boot options to nodes on both a global basis and a per-node basis. See Linux kernel parameters (kernel.org) for a full listing of available options.

Global kernel boot options

To set kernel boot options globally, as an admin, open the 'Settings' page and on the 'General' tab scroll down to the 'Global Kernel Parameters' section:

global kernel options

Type in the desired (space separated) options and click 'Save'. The contents of the field will be used as-is. Do not use extra characters.

See MAAS CLI for how to do this with the CLI.

Per-node kernel boot options

Per-node kernel boot options are set using the CLI. See MAAS CLI for instructions.

Note that per-node boot options take precedence to global ones.
