I have followed the steps mentioned in this thread:
to create a uio0, but EAL complains about the following:
--
EAL: Cannot open /sys/class/uio/uio0/device/config: Permission denied
EAL: Error - exiting with code: 1
Cause: Requested device 0000:00:19.0 cannot be used
--
even though I run as a root user and have all the rw permissions. Can
anybody tell me what else I could be missing?
Thanks,

I have tried everything from 400 to 777 (rwx permissions on the config
file) on the host (which gets reflected in the container as well), but
still EAL complains it cannot open the file. Any ideas/workarounds for
this issue, please?. If I do it from the host, it works fine..
