Hi, The lxc-users mailing-list would probably have been more appropriate for this. Your listing above shows devices that are 7:* yet you're allowing 162:*, that's not going to do you much good :) They also won't be created in the container unless they're created by default by udev or you're getting a matching uevent. As those seem like virtual devices bound to a kernel module, I don't think they'll get auto-created, so you'll need to use mknod in the container to create the node, then you should be able to use it. Note that I also wrote an lxc-device tool which we ship in recent LXC and lets you add new devices to your container after boot (not persistent though). Using lxc-device you should be able to do: lxc-device add -n <container-name> /dev/raw/raw1 And /dev/raw/raw1 should appear in the container and be usable (you may have to create /dev/raw first, I'm not sure lxc-device creates missing directories). > > Yet, the raw devices are not accessible in the container: > > ls -la /dev/raw/ > total 8 > drwxr-xr-x 2 root root 4096 Oct 2 09:29 . > drwxr-xr-x 6 root root 4096 Oct 8 06:08 .. > > Any ideas? > > Thank you, > Dragos -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
