[Users] Bind mounts and/or additional disk volumes
I'm experimenting with using OpenVZ for shared-root guest VMs. Thus far I have managed to get most of it working using GFS for /vz/private. I can start up the same guest on two different hosts (both of which mount the same /vz/private GFS volume), and both guests come up fine without trashing the file system. The problem is that I also need each guest to have some private disk space, e.g. under /cdsl.local. I have tried to work around this by bind-mounting /vz/local to /vz/private/1/cdsl.local on the two hosts before starting the VMs. However - this doesn't appear to have the desired effect. The guests still see the GFS file system rather than the bind mount that was mounted there before the VM started. This would imply that the guest VM sees only the fs mounted under /vz/private/VMID, rather than the aggregate file systems that might be mounted there. Is this a bug, or is this intended behaviour? Further, since bind-mounting such private volumes from the host doesn't seem to work, how do I add a private disk volume of some description inside the guest?

You need to mount into root instead, which in itself is a hidden bind mount which is only available as long as the VE is mounted. I'm not entirely sure I follow what you mean. Can you please elaborate? How do I mount things into root? You can use the mount and umount VE scripts to do your work. Can you provide an example or a link to the relevant docs or wiki page?

Re: [Users] Bind mounts and/or additional disk volumes
The root area is at: /var/lib/vz/root/$VEID This point exists only if container is running. Yo can create mount/umount scripts too: http://wiki.openvz.org/Bind_mounts Greetings.

Re: [Users] Seeing Boot Progress for Guest VM
I just built this into an rpm package and it builds fine (after adding the line to the spec file for init-logger), but at run-time it looks for init-logger in /usr/lib instead of /usr/lib64. Is there a way to fix that? Other than moving it? Gordan Dietmar Maurer wrote: The output of init is written to /var/log/init.log (inside the container).
