Comment 1 for bug 1507921

For openvswitch-dpdk, vm.max_map_count should be adjusted at least for 2*nr_hugepages + some padding for other apps, e.g.:

    max_map_count="$(awk -v padding=65530 '{total+=$1}END{print total*2+padding}' /sys/devices/system/node/node*/hugepages/hugepages-*/nr_hugepages)"
    sysctl -q vm.max_map_count=${max_map_count:-65530}
