Hi, I am getting the following error while running testpmd:
RING: Cannot reserve memory EAL: Error - exiting with code: 1 Cause: **** Creation of mbuf pool for socket 0 failed I am running it thus: build/app/testpmd --log-level 8 -c7 -n3 -- \ -i --nb-cores=2 --nb-ports=2 --pkt-filter-mode=perfect And I followed the instruction on http://dpdk.org/doc/quick-start However, on my machine, as opposed to what appears in the link above, there is no /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepage , and under /sys/devices/system/node I have only a single node called "node1". I don't know what is the reason for this, this is Fedora 23 x86_64 standard distro and a standard kernel (4.2.3-300.fc23.x86_64), and on a different machine I **do** have node0. So instead echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages I run echo 64 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages Could this be related somehow to the problem I have ? More info: This is a 16 core machine. I also delved a bit into the code and added a debug message which prints the pool name in the method where the failure occur, mbuf_pool_create(), and this is what I see: calling rte_pktmbuf_pool_create(), pool_name=mbuf_pool_socket_0 in mbuf_pool_create Any ideas ?
