 Now create a cached OS tarball.  In the command below, you'll want to replace <arch> with your architecture (i386, amd64, ia64, etc). '''Note the space and the dot at the end of the command'''.
-  [HW]# tar czf /vz/template/cache/ubuntu-7.10-<arch>-minimal.tar.gz .
+  [HW]# tar --numeric-owner -czf /vz/template/cache/ubuntu-7.10-<arch>-minimal.tar.gz .
 Look at the resulting tarball to see its size is sane:

	Note: Older versions of vzctl are working if you install <code>sysvinit</code> (which will remove <code>upstart</code>). The only problem I had was the network did not start, so I added "/etc/init.d/networking restart" to /etc/re.local.

−	Note: Original author needs explanation of how to retrieve vzctl. I have Fedora 8, I believe I used yum install ovzkernel to install and somehow I had a complete installation with entry added to /boot/grub/menu.lst. I rebooted and selected the new added entry and it worked, however I did not go far enough to make the containers. I would still like to try the steps on this tutorial though.
