Hi Serge,

git clone git://github.com/lxc/lxc
cd lxc
sh autogen.sh

set the paths
./configure
make
sudo make install

It was necessary to run 'ldconfig' and install 'debootstrap', then:

sudo lxc-create -t ubuntu -n p1

Where can I grab this debian/ tree ?

https://github.com/lxc/lxc has 3 branches: 'master', 'stable-0.74' and
'stable-1.0'

I got https://linuxcontainers.org/downloads/lxc-1.0.3.tar.gz

There is no such 'debian/rules'

$ ps -ef | wc -l
227
$ ps -ef | grep mount
phiho     1792  1298  0 13:15 pts/0    00:00:00 grep mount

​I don't quite understand ​ "the only things running in
 ​
the container are 3 or 4 tasks".
The container cannot be started:

$ sudo lxc-ls
p1
$ sudo lxc-start -n p1 -d
lxc-start: command get_cgroup failed to receive response
$ sudo lxc-info -n p1
Name:           p1
State:          STOPPED

Best regards,

PhiHo
