try o increase the hugepages to
4GB and run once again.
Also it depends on how much memory u are reserving in mempools and for
rings..

Re: Unable to start DPDK+Netshard

[harshavardhan Reddy]

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

Harsha
