Well I found a thread in the mailing list archive that said:
"- reserve space on your /vservers partition for a template
- dump/restore or cp -va or whatever, your existing host system there
- cleanup the template with simple chroot, i.e. remove packages and
stuff you won't need in a guest, adjust the startup/shutdown scripts to
avoid hardware stuff
- clear out /proc and /dev inside the template
now this is only required once, and will save you a lot of space later ...
to create a new guest, use the 'skeleton' method with all the desired
config options, then copy over the template into the skeleton guest dir"

So what I did was copied my host system into a directory (called it
template). I used the skeleton method to build a guest called sk (with
appropriate interface and hostname given). Then I copied the template
into the guest. I think where I went wrong is the cleanup of the
template, I'm not sure what I should clean out and what I should leave.
I think I have either left some scripts that are not needed or deleted
something that is needed, but I don't understand what.
Any help would be appreciated.
