lxc isn't needed to reproduce this. You can simply mount an overlayfs with lowerdir set to an nfs mounted directory, then ls in the overlay mount, and get an oops. That was in precise.

@Dan, would you mind doing apport-collect 1051080 as requested above? I do notice that even on quantal, where the kernel bug does not appear to exist, lxc-start-ephemeral still fails with nfs-backed directories. If you run into that, please submit a new bug against lxc for that rather than re-using this one. I will mark this particular bug as invalid against lxc, as this is a kernel bug.

[Bug 1051080] Re: lxc-start-ephemeral hangs if bind mounting nfs homedir
apport information ** Tags added: apport-collected precise ** Description changed: On Ubuntu 12.04.1, ephemeral containers seem to conflict with NFS home directories. The user's home directory is on a remote NFS server.

[Bug 1051080] [NEW] lxc-start-ephemeral hangs if bind mounting nfs homedir
You have been subscribed to a public bug: On Ubuntu 12.04.1, ephemeral containers seem to conflict with NFS home directories. The user's home directory is on a remote NFS server. The original container is created with sudo lxc-create -t ubuntu -n foobar -- -r lucid --bindhome $LOGNAME The ephemeral container is started with lxc-start-ephemeral -o foobar The user logs in to the ephemeral container. This hangs. After that, any reference to the home directory -- inside or outside of the container -- seems to hang. mount in the container shows: none on / type overlayfs (rw,relatime,lowerdir=/var/lib/lxc/buildhost2-ubu10,upperdir=/tmp/lxc-lp-v92y7NU) none on /mnt/home/builder type overlayfs (rw,relatime,lowerdir=/mnt/home/builder,upperdir=/var/lib/lxc/buildhost2-ubu10-temp-loNNGB5/ephemeralbind/mnt/home/builder) mount outside the container shows: obnas1a:/vol/homes/builder 419430400 362328576 57101824 87% /mnt/home/builder But sometimes, mount outside the container shows nothing for /mnt/home/builder after the problem happens.
