Hi!
I'm trying to use lxc-checkpoint to dump/restore simple lxc container.
I added:
|# hax for criu
lxc.console = none
lxc.tty = 0
lxc.cgroup.devices.deny = c 5:1 rwm|
to container config, but when I'm trying to run
|lxc-checkpoint -n $name -D $checkpoint_dir -s -v|
I get:
Error (mount.c:624): 113: ./sys/fs/cgroup/perf_event doesn't have a
proper root mount
Could you give me a hint on what is going on?
I also saw that other people do experience the same problem:

Thanks,
Ruslan
