[lxc-users] problems or only warning (!?) with lxc-clone

[Yonsy Solis]

Hi

i create a base container with the minimal needed for works: zsh, 
oh-my-zsh, updated Ubuntu 14.04.2 packages, user with admin/sudo 
rights, bye root ssh logins, ssh only by certificate, no ssh passwords, 
cleaned apt archives, cleaned logs, etc a little paranoid in security.

for new containers i clone all from this base container, and I get this 
message:
===
host15 :: ~ » lxc-clone -s baseserver testserver
newgidmap: gid range [100000-100001) -> [200000-200001) not allowed
error mapping child
setgid: Invalid argument
Created container testserver as snapshot of base
===

With this warning, the container is cloned. I work this with user 
lazarus
===
host15 :: ~ » cat /etc/subgid /etc/subuid

is normal this warning or a possible error is growing without notice ? 
somebody can explain me why this warning ?
