[lxc-users] Problem with memory.memsw.limit_in_bytes on Ubuntu 14.04.

[PONCET Anthony]

Hello,
I'm trying to used the memory.memsw.limit_in_bytes, and I have this 
error when I trying to set this : "lxc-cgroup -n c_name 
memory.memsw.limit_in_bytes 2G
lxc_container: cgmanager.c: do_cgm_set: 1013 Error setting cgroup value 
memory.memsw.limit_in_bytes for memory:/user/1001.user/2.session
lxc_container: cgmanager.c: do_cgm_set: 1014 call to 
cgmanager_set_value_sync failed: invalid request
lxc_container: lxc_cgroup.c: main: 103 failed to assign '2G' value to 
'memory.memsw.limit_in_bytes' for 'c_name'".
The memory.limit_in_bytes work perfectly.
I've trying to add swapaccount=1 in grub, but no more result.
I try to used it with unprivileged container or classic, and I have a 
same result.
Kernel : 3.13.0-46-generic (AMD64).
