Edit the /etc/default/grub file, and add the following to the
GRUB_CMDLINE_LINUX entry:
GRUB_CMDLINE_LINUX="hugepagesz=1G hugepages=<Number of hugepages required>
default_hugepagesz=1G"
There only you can mention cpu isolation also.
After modifying run
grub2-mkconfig -o /boot/grub2/grub.cfg
reboot system
Regards,
Harsha
