Hi Serge,
Sorry I am not cleared; Please see my answers pointwise:
>>i don't understand what you've done, what you wanted to have happen, or what
>>actually happened.
I took a busybox based filesystem which doesn't have any lxc-container support.
So I downloaded the lxc-1.1.0 package & After cross compiling the lxc package I
installed the binaries in busybox file system.
Our aim is to support linux container on busybox based filesystem. So that we
can boot android or busybox over linux container.

I use "root" as a login to busybox file system. Till now I have not created any
container. I logged in as a root into busybox file system.
>>what do you mean exactly, is that logged in over lxc-console with the
>>container running?
No, I havenot created any container till now. After login into busybox
filesystem, Now I create a container named "bb" using lxc-create. Now after
creating the container, I can see the rootfs present in /var/lib/lxc/bb
directory, that means container successfully created.
>> Why did you create the 'root' cgroups by hand?
We didn't have cgmanger to handle the cgroup so I created a root entry in
cgroup.
>> or what actually happened?
After doing all above, when I started a container using "lxc-start" it fails
with invalid pid. As follows:
lxc-start 1414573214.442 DEBUG lxc_conf - conf.c:setup_caps:2139 -
capabilities have been setup
lxc-start 1414573214.442 NOTICE lxc_conf - conf.c:lxc_setup:3921 -
'bb' is setup.
lxc-start 1414573214.442 NOTICE lxc_start - start.c:start:1232 -
exec'ing '/sbin/init'
lxc-start 1414573214.482 NOTICE lxc_start - start.c:post_start:1243 -
'/sbin/init' started with pid '1896'
lxc-start 1414573214.482 WARN lxc_start - start.c:signal_handler:307
- invalid pid for SIGCHLD
Please let me know if I unclear on any point.
Regards,
Praveen

I'm sorry, i don't understand what you've done, what you wanted to have
happen, or what actually happened.
Exactly how did you create the container? When you say "I am login as a root
in buysbox file system", what do you mean exactly, is that logged in over
lxc-console with the container running? Why did you create the 'root' cgroups
by hand?
