[dpdk-users] EAL hugetables initialisation with 2 NUMA nodes broken in 18.08

[Pavan Kumar]

Hi,


I have a centos VM running on ESXi 6.7 server. VM CPU is configured with
only one physical socket. 2 NUMA nodes are detected based on the number of
CPU assigned to the VM. Prior to 18.08 when 2 NUMA nodes were detected
hugetable initialisation worked fine. With 18.08 it fails. Below is a snap
shot of the error.  Kindly help me resolve this issue.
