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
0000:00:14.2 'Ethernet Connection I354' if=eth2 drv=igb unused=igb_uio
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
