It’s also strange you get -1 as the NUMA socket. EAL: PCI device 0000:02:00.0 on NUMA socket -1
Maybe you could have the same issue if you keep OVS off and just run some simple DPDK test application? For ex by running testpmd, so no OVS process is involved. Also, as this is an error message coming from DPDK code – and especially if you still have the same issue with a DPDK app without OVS - it could be a good idea to post also to the DPDK Mailing-list.

Antonio From: discuss [mailto:discuss-boun...@openvswitch.org<mailto:discuss-boun...@openvswitch.org>] On Behalf Of Charlie Li Sent: Friday, June 24, 2016 4:36 PM To: discuss@openvswitch.org<mailto:discuss@openvswitch.org> Subject: [ovs-discuss] pci_map_resource(): cannot mmap(..): Invalid argument (0xffffffffffffffff) Hello, I am trying to set up openvswitch-2.5.0 with DPDK-2.2.0 by following "INSTALL.DPDK.md<http://INSTALL.DPDK.md>". 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
