libvirt users - May 2015 - Drivers supporting space_hard_limit

Hi,

In the XML documentation I found the element space_hard_limit for
filesystems [1]. Is this feature implemented for any constellation?

I try to use it with lxc 1.0.6-6 and libvirt 1.2.9-9 (all from debian
jessie):

<domain type='lxc' id='1234'>
  ....
  <devices>
    <emulator>/usr/lib/libvirt/libvirt_lxc</emulator>
    ....
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/tmp/libvirt/mnt'/>
      <target dir='/mnt'/>
      <space_hard_limit
unit='bytes'>5242880</space_hard_limit>
    </filesystem>
    ....
  </devices>
</domain>

For testing I use dd if=/dev/zero of=/mnt/foo and ^C after a few gigabytes.

Is this a supported configuration? If yes, I can provide some more info
to reproduce, if not, I think this should be noted in the docs ("Only
used by ??? driver").

Thanks,
Christian

Hi again,

it seems this feature is not just for me unclear. Is somebody using this
feature? If yes, what is your environment?

Cheers,
Christian
