We have good experience of running OpenVZ (http://openvz.org) with Owl
as the H/W node OS and Owl inside VPS environment.
Quick steps to create a test bed are the following:
1. download ovzkernel, vzctl, vzctl-lib, and vzquota .
2. rpm -Uvh vz* --nodeps # there are some deps which can be safely
ignored.
3. intall ovzkernel (I'm building it from sources, but you might want to
use a binary package)
4. create an empty template by doing the following:
# cd /vz/template/cache
# touch empty.txt
# tar czf empty.tar.gz empty.txt
# rm empty.txt
5. initiate the initial VPS that wouldbe used as a template:
# vzctl create 100 --os-template empty
(there will be some errors during the execution of this command but
they can be ignored)
6. install Owl into /vz/private/100 by modifying installworld.conf and
executing 'make installworld' .
7. add 'route add default venet0' to /vz/private/100/etc/rc.d/rc.local and
make this file executable.
8. you are readyto start VPS 100 with vzctl start 100 .
9. once you are satisfied with the configuration of the VPS OS, shutdown
the VPS with vzctl stop 100
a. remove /vz/private/100/etc/ssh/ssh*_host* (host keys)
b. tar czSf /vz/template/cache/owl-2.0.tar.gz --one-file-system -C /vz/private/100 .
c. From now on, you will be able to create Owl-based VPSes with
vzctl create <VEiD> --os-template owl-2.0
P.S. I've typed all of this directly from my head, but I believe that
the commands are correct.
