Sorry, there is a typo, it should be: lxc.mount.entry=/mnt/huge /var/lib/lxc/$container_name/rootfs/mnt/huge none rw,bind 0 0

I have installed the driver module for this device on the host. When I run the application on the container it complains it is unable to find the device in the /dev file system. Infact I use UIO based driver. So in container I get message unable to access /dev/uio0: No such file or directory.
