does not solve the problem.
on host:
gs ~ # vzctl mount 2001
VPS is mounted
gs ~ # mount /usr/portage /vz/root/2001/usr/portage -o bind,ro
gs ~ # mount
/dev/hda1 on / type ext3 (rw,noatime)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
/dev/hdb1 on /tftproot type ext3 (rw,noatime)
shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev)
192.168.39.1:/home/lmeier on /root/lmeier type nfs (rw,addr=192.168.39.1)
none on proc type proc (rw)
/usr/portage on /vz/root/2001/usr/portage type none (ro,bind)
gs ~ #
in the VPS:
ovz01 usr # ls
bin include libexec portage sbin src
i386-pc-linux-gnu lib local portage.vps share tmp
ovz01 usr # ls -l portage
total 0
