The network issue is partly solved: I do not use the gentoo net.lo script for
net.venet0 anymore, instead I setup the interfaces venet0 and venet0:0 with
the attached workaround-script.
But, how do I bind-mount directories from to host to the VPS, e.g. to
use /usr/portage in the VPD too. If I try to (on host)
gs ~ # mount /usr/portage /vz/private/2001/usr/portage/ -o bind,ro
I get
ovz01 usr # ls
bin i386-pc-linux-gnu include lib libexec local portage sbin share
src tmp
ovz01 usr # ls portage
ovz01 usr #
on the VPS ovz01. Whats wrong?
