Thanks for replaying me.
I also tried some times in different configuration, here are details:
I corrected the line in fstab "none /lxc/rootfs.ubuntu/dev/pts devpts
defaults 0 0" to right path, failed.
I comment the line above, failed.
I change the whole fstab using
http://wiki.1tux.org/wiki/Lxc/Installation/Guest/Centos/6 provides, failed.

All the things happened as the same.
I also changed the lxcguest.conf (the original one is provided by the
package lxcguest) to this (which is found in a previous mail list):

start on startup

env container
env LIBVIRT_LXC_UUID

script
        rm -rf /var/run/*.pid
        rm -rf /var/run/network/*
        /sbin/initctl emit stopped JOB=udevtrigger --no-wait
        /sbin/initctl emit started JOB=udev --no-wait
end script

Failed as well, but the /sbin/init shows different result:

init: Handling startup event
init: lxcguest goal changed from stop to start
init: lxcguest state changed from waiting to starting
init: hostname goal changed from stop to start
init: hostname state changed from waiting to starting
init: Handling starting event
init: lxcguest state changed from starting to pre-start
init: lxcguest state changed from pre-start to spawned
init: lxcguest main process (4)
init: lxcguest state changed from spawned to post-start
init: lxcguest state changed from post-start to running
init: Handling starting event
init: hostname state changed from starting to pre-start

init: hostname state changed from stopping to killed
init: hostname state changed from killed to post-stop
init: hostname state changed from post-stop to waiting
init: Handling stopped event
init: Connection from private client
