I have created a tool to clone (even a running) vserver. It is available
from the Debian vserver package (in the debian/ dir in the Debian source too).
It is called dupvserver. What it does is in fact just a rsync of the directory
(so i plan to extend it to copy the files to an other host) with /proc/
and /dev/pts/ excluded. Then it changes the name of the host and ip in the
configuration and also in /etc/hosts (etc) inside the new vserver.
Most intrersting parts is here:
rsync -a --delete \
--exclude=/proc --exclude=/dev/pts\
$VSERVERS_ROOT/$FROM/ $VSERVERS_ROOT/$TO
mkdir -p $VSERVERS_ROOT/$TO/proc
mkdir -p $VSERVERS_ROOT/$TO/dev/pts
In Debian I have patched vserver to allow other directories than /vservers, so
that is the reason for $VSERVERS_ROOT.
