I'm following the guide to run X apps in a container at:

As a starting point, I have a normal unprivileged container running
perfectly. However when I change the id_map configuration to look
like:
lxc.id_map = u 0 100000 1000
lxc.id_map = g 0 100000 1000
lxc.id_map = u 1000 1000 1
lxc.id_map = g 1000 1000 1
lxc.id_map = u 1001 101001 64535
lxc.id_map = g 1001 101001 64535
the container fails to start, claiming:
chris@d6:~/.local/share/lxc$ lxc-start -n x11-test-x86_64 -F
newuidmap: uid range [1000-1001) -> [1000-1001) not allowed
lxc-start: start.c: lxc_spawn: 1161 failed to set up id mapping
[...]
Can anyone shed light on this problem please?
You've got to add the id to /etc/subuid and /etc/subgid. Example:
chris:1000:1
chris:100000:65536
Thanks Andreas,
I had the second line but not the first. The container starts without
error now.
