[dpdk-dev] dpdk_nic_bind giving error

[Vipin Agrawal]

I’m running on centos with kernel 3.18.3 and built the dpdk with gcc 4.7 and running with python 3.3

When trying to get status or even trying to bind to the eth0 port, I get the following error :

[root@linux-dt dpdk-1.8.0]# tools/dpdk_nic_bind.py --status
Traceback (most recent call last):
  File "tools/dpdk_nic_bind.py", line 536, in <module>
    main()
  File "tools/dpdk_nic_bind.py", line 532, in main
    get_nic_details()
  File "tools/dpdk_nic_bind.py", line 225, in get_nic_details
    dev_lines = check_output(["lspci", "-Dvmmn"]).splitlines()
  File "tools/dpdk_nic_bind.py", line 120, in check_output
    stderr=stderr).communicate()[0]
  File "/usr/lib64/python2.6/subprocess.py", line 642, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.6/subprocess.py", line 1234, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory


What am I doing wrong?

Looks like you don't have pci-utils installed.  The script can't find the lspci
utility
