Can you try to specify the socket memory parameter --socket-mem 1024,0 ? So the command sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach
becomes sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 --socket-mem 1024,0 -- unix:$DB_SOCK --pidfile –detach From: Charlie Li [mailto:charlie...@gmail.com] Sent: Tuesday, June 28, 2016 4:41 PM To: Fischetti, Antonio <antonio.fische...@intel.com> Cc: discuss@openvswitch.org Subject: Re: [ovs-discuss] pci_map_resource(): cannot mmap(..): Invalid argument (0xffffffffffffffff) Hi Antonio, Please see the dumps in the attached file.

First tried with Ubuntu server 16.04 and it worked as expected. But when tried with Fedora server 23, it hit the following error EAL: pci_map_resource(): cannot mmap(10, 0x7f1800000000, 0x80000, 0x0): Invalid argument (0xffffffffffffffff) when invoking sudo ./ovs-vswitchd --dpdk -c 0x1 -n 4 -- unix:$DB_SOCK --pidfile --detach I tested it on the same hardware platform and followed the same instructions. Why it only failed with Fedora? I am also attaching the detailed logs from both Ubuntu (working case) and Fedora (failing case). Any help is appreciated. Thanks, Charlie
