The difference between DISKSPACE=unlimited and DISK_QUOTA=no
is in the first case disk quota is initialized, disk space is accounted for,
it's just that the limit is high enough to be reached in practice.

In the case of DISK_QUOTA=no disk quota for CT is not initialized
at all -- so this I guess is preferable approach if you don't want to
impose any limits for CT disk space usage.

Yes, this is a bug, thanks for reporting that one (although bugzilla is
a better place for bug reports).

I took some time and fixed it in vzctl git. In addition, I have
added "vzctl set --diskquota yes|no" and fixed man pages
and bash completion script accordingly. Below are the links
to patches, in case you want to try it. Alternatively, these
fixes should appear in vzctl >= 3.0.25.


Fix itself:

Add description of DISK_QUOTA into ctid.conf(5) man page:

vzctl set: implement --diskquota on|off:
http://git.openvz.org/?p=vzctl;a=commit;h=5c63ca79

Fix for the above patch to work:

If you want to apply these patches to e.g. vzctl-3.0.24.2 and test,
you might need to take this patch as well, since others depend on it.
Move set_opt[] to where it belongs:
