Hmm, I've not seen this on vivid. Can you describe how to reproduce it and I'll take a look? > with ubuntu 14.04 I get this: > > ... > (00.003608) autodetected external mount /sys/fs/pstore/ for ./sys/fs/pstore > (00.003610) autodetected external mount /sys/kernel/security/ for > ./sys/kernel/security > (00.003611) autodetected external mount /sys/kernel/debug/ for > ./sys/kernel/debug > (00.003613) autodetected external mount /sys/fs/fuse/connections/ for > ./sys/fs/fuse/connections > (00.003620) Error (mount.c:680): FS mnt ./sys/kernel/debug/tracing dev 0x9 > root > / unsupported id 130 > ... > (00.003719) Error (cr-dump.c:1618): Dumping FAILED. > > (using latest ubuntu 4.1 kernel) > > I guess this is related to lxcfs? Not quite, can you show /proc/<container init pid>/mountinfo? I think this should be autodetected by criu the same way the other mounts are, but apparently it is not.
