Custom boot kernel arguments can be added to RHVH hosts from the Cockpit user interface 'terminal' tab, using grubby tool commands. Steps for using grubby tool are described here: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sec-Making_Persistent_Changes_to_a_GRUB_2_Menu_Using_the_grubby_Tool.html A link to the RHEL 7 document above, and a brief explanation of modifying boot kernel arguments, must be added to the documentation for RHVH.
Assigning to Tahlia for review.
