Specifying kernel parameters

Red Hat Enterprise Linux 8.6 LPAR mode z/VM guest KVM guest

Different methods are available for passing kernel parameters to Linux®.

  • Including kernel parameters in a boot configuration
  • Using a kernel parameter file
  • Specifying kernel parameters when booting Linux

Kernel parameters that you specify when booting Linux are not persistent. To define a permanent set of kernel parameters for a Linux instance, include these parameters in the boot configuration.

Note: Parameters that you specify on the kernel parameter line might interfere with parameters that Red Hat® Enterprise Linux 8.6 sets for you. Read /proc/cmdline to find out which parameters were used to start a running Linux instance.
