I deployed openstack with dpdk-ovs and I'm now testing it. The problem is that a NIC which is binding to igb_uio module of DPDK is physically down so that it seems not communicate with the other hosts through the NIC. The test environment is as below: OS: RHEL 6 with kernel 3.7.10 Hardware information: Intel Atom Processor C2758, 64GB DDR3, 4x RJ45 Gigabit Ethernet LAN ports, etc. DPDK version: 1.7.0 ovdk version: 1.1 I checked the NIC's status via ./tools/dpdk_nic_bind.py --status, and it doesn't snow *Active* status: ./tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver ============================================ 0000:00:14.1 'Ethernet Connection I354' drv=igb_uio unused=igb Network devices using kernel driver =================================== 0000:00:14.0 'Ethernet Connection I354' if=eth0 drv=igb unused=igb_uio *Active* 0000:00:14.2 'Ethernet Connection I354' if=eth2 drv=igb unused=igb_uio *Active* 0000:00:14.3 'Ethernet Connection I354' if=eth3 drv=igb unused=igb_uio Other network devices ===================== The NIC port on the PC doesn't glitter physically, which means it seems not connected physically. Doesn't the processor support DPDK, or what is causing the problem? Any comments would be really appreciated. Best Regards Byeong-Gi KIM
