Looks like you have set 1GB as > default hugepage size. Actually the output log is the complete opposite!!!That log is simply stating that you have _NOT_ reserved 1GB hugepages but rather the 2MB ones.

Apparently the hugepages allocation has run out on one of the two socket and it's _warning_ you that memory will be taken from the other one. It's warning you because it's a performance hit to access remote-node memory...Again this is a _warning_ not an error. Having said all that, why don't you follow this page (DPDK) on how to reserve hugepages for NUMA machines?https://doc.dpdk.org/guides/linux_gsg/sys_reqs.htmlSomething like:echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages- 2048kB/nr_hugepages > > Sep 06 16:30:55 turing-04 vnet[2339]: dpdk_ipsec_process:1018: not enough > > DPDK crypto resources, default to OpenSSL > > Sep 06 16:30:55 turing-04 vnet[2339]: dpdk_lib_init:230: DPDK drivers found > > no ports... You have not binded any port to be used by DPDK... again, take a look at this webpagehttps://doc.dpdk.org/guides/tools/devbind.htmlSomething like dpdk-devbind --bind=vfio-pci PCI_BAR_ADDRESSwill map your port (identified by PCI_BAR_ADDRESS) to the vfio-pci driver. > > Thanks, > > Arijit. - Marco > > > > On Thu, Sep 6, 2018 at 9:44 AM Avinash Dhar Dubey <mailbox.avin...@gmail.com > > > wrote: > > > Arijit, > > > > > > > > > We are using Intel X540 NIC. > > > >> Intel X540 NIC is supported by DPDK. > > > > > > > > > > > > I'll try with one of them.
