I was playing with a container today, we took the following actions:
. Change from static to DHCP IP
. Shut down container, add an fstab entry to LXCs fstab file
. Started, failed to start
. Undid all changes, re-configured static IP and removed the fstab
entry
Now when I try to start the container I see this in the debug log -o
debugfile -l DEBUG:

I can connect to the console, but I get nothing back from the console, I
can't SSH to the container, it just appears hung. We had this container
running fine for weeks now, only on the restart did I get this, and I'm
reasonably confident that we un-did any changes we had made in our testing.
