[lxc-users] Number of core for a container

[Stéphane Graber]

Those instructions are for LXD, not for low level LXC.

For LXC, you'd need to use the lxc.cgroup.cpuset config keys to directly
configure the cpuset cgroup.

Note that since LXC doesn't have a long running manager like LXD does,
you're going to need to do the scheduling/balancing of those containers
yourself.
