On the multi NUMA node environment, kernel splits hugepages allocated under /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages file equally between NUMA nodes. That makes it harder to predict where several pods will start because the number of hugepages on each NUMA node will depend on the amount of NUMA nodes under the environment. The memory manager test will allocate hugepages on the specific NUMA node to make the test more predictable on the multi NUMA nodes environment. Signed-off-by: Artyom Lukianov <alukiano@redhat.com>
