Section number and name: Procedure G.2. Enabling IOMMU Manually
Describe the issue: In the second step: Refresh the grub.cfg file and reboot the host for these changes to take effect, the command grub2-mkconfig -o /boot/grub2/grub.cfg will not take in the command-line arguments from BLS inheritance.
Impact of this issue: This wil cause editing /etc/default/grub's command line argument not take effect when build new gtub and reboot, making configuring IOMMU failed.
Suggestions for improvement: Specify how to build correct grub with option --update-bls-cmdline for correct RHEL version.
