Loading and unloading of kernel modules

The Kernel modules on a system can be managed cleanly with the kmod state module:

add_kvm:
  kmod.present:
    - name: kvm_amd
remove_beep:
  kmod.absent:
    - name: pcspkr

Multiple modules can be specified for both kmod.present and kmod.absent.

add_sound:
  kmod.present:
    - mods:
      - snd_hda_codec_hdmi
      - snd_hda_codec
      - snd_hwdep
      - snd_hda_core
      - snd_pcm
      - snd_timer
      - snd

salt.states.kmod.absent(name, persist=False, comment=True, mods=None)

Verify that the named kernel module is not loaded

name

The name of the kernel module to verify is not loaded

persist

Remove module from /etc/modules

comment

Comment out module in /etc/modules rather than remove it

mods

A list of modules to verify are unloaded. If this argument is used, the name argument, although still required, is not used, and becomes a placeholder

salt.states.kmod.present(name, persist=False, mods=None)

name

The name of the kernel module to verify is loaded

persist

Also add module to /etc/modules

mods
