linux_vserver_debian_etch tutorial : can not create guests

[fortuitude]

Hello, everybody!

I have followed the steps described on the tutorial of daniel15 about the set up of guests virtual machines. The tutoriel is about Etch, but I am running a lenny, with the 2.6.26 kernel. Both versions should be close enough to let me do such thinks.
Everything is fine during the configuration of the host and I can reboot withour problem on my vserver kernel.

When I try to create a vserver guest, through this command:

newvserver --vsroot /var/lib/vservers --hostname test1 --domain genepi-9.local --ip 10.183.0.1/16 --dist etch --mirror http://ftp.fr.debian.org/debian --interface eth1

the output is like:

VxID: 0
I: Retrieving Release

and then it hangs...
I have tried other distributions (lenny for instance) with the same result.

I have the following lines on /var/log/syslog

May 24 11:59:15 genepi-9 kernel: [ 2195.646241] Not cloning cgroup for unused subsystem ns

When I try to cancel the building of the guest (Ctrl+C) I get this
chroot-sh: open("/etc/apt/sources.list"): No such file or directory
chroot-sh: open("/etc/apt/apt.conf"): No such file or directory
However these files exist where they are supposed to :-S

Can anyone help me, finding out what's happening?

Thanks
