Setup lxc container on ubuntu 10.04 (inside virtualbox)

On host
[bash]
$ cd ~
$ sudo apt-get lxc
$ sudo mkdir /var/local/cgroup
$ sudo vi /etc/fstab
# add this line:
# cgroup /var/local/cgroup cgroup defaults 0 0
$ sudo mount cgroup
$ git clone https://github.com/phbaer/lxc-tools.git
$ cd lxc-tools
# change ubuntu mirror to http://cn.archive.ubuntu.com/ubuntu in the next screen
$ sudo lxc-ubuntu create -n guestos001
# above command would take a long time like half or one hour
$ sudo vi guestos001/config
# change lxc.network.line = virbr0
# to setup a bridge between lxc container and guest os
$ sudo apt-get install libvirt-bin
# start and set root password
$ sudo lxc-start -n guestos001 /bin/bash
$ passwd # set password for root
# close it from another host session
$ sudo lxc-stop -n guestos001
# start it again
$ sudo lxc-start -n guestos001
# the console will hang there no input accepted
[/bash]

On another session of host
[bash]
$ sudo lxc-console -n guestos001
# loggin with root and its password
# Now you are in guestos
# restart network, if neccessary
$ sudo mkdir /var/run/network
$ sudo /etc/init.d/networking restart

# add user
$ adduser pxiao --home /home/pxiao
# set password

# close it from an third session on host
$ sudo lxc-close -n guestos001
[/bash]
