 No, I didn't change the init scripts. Guest also Natty.  Any 
 particular script or log I should be looking at?

If there is no gateway after startup, then your guest's network was not 
setup by guest, only by lxc, that's why there is gateway.

Try this:

$ cat /etc/init/lxclo.conf
# description LXC vs. Upstart workarounds
start on startup
task
console output

 script
  # As lxc 0.7's halt/reboot detection hack needs /var/run to NOT be a
  # tmpfs, we need to manually clean it -- esp. the ifstate file that
  # tells falsely tells ifupdown lo is up.
  #
  # To debug, add -printf Deleting stale file %p\n before -delete.
  find /var/run/ -xdev -not -path /var/run/ -delete
  initctl emit -n stopped JOB=udevtrigger
  initctl emit -n started JOB=udev
  # This one is needed for broken ifupdown NMU 0.6.8ubuntu29.1
  initctl emit -n net-device-up IFACE=lo LOGICAL=lo ADDRFAM=inet 
METHOD=loopback
 end script



Is lxcguest deb package installed?

If not, then yeah there's nothing that can be done without the ns cgroup.

1) The ns cgroup does exist and is mounted.

2) It works with the single mount point and clone children is not
present.


To answer your question...

[mhw@berserker-base ~]$ ls /cgroup/cpuset/
cgroup.event_controlcpuset.memory_spread_page
cgroup.procscpuset.memory_spread_slab
cpuset.cpu_exclusivecpuset.mems
cpuset.cpus cpuset.sched_load_balance
cpuset.mem_exclusivecpuset.sched_relax_domain_level
cpuset.mem_hardwall libvirt
cpuset.memory_migrate   notify_on_release
cpuset.memory_pressure  release_agent
cpuset.memory_pressure_enabled  tasks

I guess not...


 Thanks for testing!

If that's all I can do, I'll do the best I can.  I'm currently up to my
eyeballs in another OpenSource project, some XAUTH coding in Openswan.
I need about 6 clones of me, I swear.  :-P

 Yes but it needs to be composed with the others :)

 Ok, cool.  So the results make perfect sense.

Sounds like we are in violent agreement then.
