[dpdk-users] running dpdk in lxc-container

[dpdk-users] running dpdk in lxc-container

[Avi Cohen (A)]

Hello,
I'm trying to run dpdk in lxc-container .
But I failed to bind  the nic to the dpdk driver (igb-uio), actually I failed  in the ./dpdk-devbind,py --status 
Is it possible  to run dpdk in lxc-container ?

I get this error:

Traceback (most recent call last):
  File "./dpdk-devbind.py", line 577, in <module>
    main()
  File "./dpdk-devbind.py", line 573, in main
    get_nic_details()
  File "./dpdk-devbind.py", line 249, in get_nic_details
    dev_lines = check_output(["lspci", "-Dvmmn"]).splitlines()
  File "./dpdk-devbind.py", line 125, in check_output
    stderr=stderr).communicate()[0]
  File "/usr/lib/python2.7/subprocess.py", line 711, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1343, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

Thanks Ravada
I've already resolve this issue by binding the devices in the host and mount the /dev/uiox/ in the lxc with mknod command
This is described here:  http://dpdk.org/ml/archives/dev/2014-October/006373.html

But when I run my dpdk application I receive this error :
EAL: Cannot open /dev/uio0: Operation not permitted
Btw - I'm running as root

Hi,
I've solved the original problem by simply installing pciutils 
But now I cannot bind to dpdk - and get this error:

./dpdk-devbind.py --bind=igb_uio 0000:04:00.0
lspci: Unable to load libkmod resources: error -12
lspci: Unable to load libkmod resources: error -12
lspci: Unable to load libkmod resources: error -12
lspci: Unable to load libkmod resources: error -12
lspci: Unable to load libkmod resources: error -12
lspci: Unable to load libkmod resources: error -12
Error: unbind failed for 0000:04:00.0 - Cannot open /sys/bus/pci/drivers/ixgbe/unbind
