From 1738c931ab93816007b5434c17d46842e488424a Mon Sep 17 00:00:00 2001 From: Rodolfo Alonso Hernandez Date: Tue, 6 Feb 2018 10:34:33 +0000 Subject: Improve SampleVNF hugepages setup The goal of this function is to: - Read the default hugepage size. - Set 16GB of hugepages. - Check if the status of the last action. According to [1], the default hugepage size could be read in "/proc/meminfo", always in kB. Then "/proc/sys/vm/nr_hugepages" could be used to set the number of default hugepages.
