[libvirt] [PATCH]LXC doc: Add warns if net namespace not enabled



From: Chen Hanxiao <chenhanxiao cn fujitsu com>

If we don't enable network namespace, we could shutdown host
by executing command 'shutdown' inside container.
This patch will add some warnings in LXC docs and give some
advice to readers.
