Hi Salman,

you can checkout the directory in our stable/diablo branch in our repos in


You need to configure it as follows:

- NovaVolume nodes must have access to qemu-img executable. Otherwise it
won't be able to create the nodes.
- Share a filesystem for the volumes, for example /var/lib/nova/volumes
- in the configuration file of NovaVolume, you need to enter this flags:
flags.DEFINE_string('volumes_path', '/var/lib/nova/volumes', 'shared
directory for the volumes virtual disks')
flags.DEFINE_string('volumes_path_testfile', '%s/testfile' %
FLAGS.volumes_path, 'Test file to check if qemu-img works')
flags.DEFINE_string('volume_driver', 'nova.volume.nas.QEMUDriver', 'QEMU
Volumes driver')

We have an experimental release in our 0.4 version of the StackOps Distro
and in our Enterprise Distro, hopefully to release in the coming weeks.

  We have developed a QEMUDriver for stable/diablo, sadly the essex build
  is still broken. We are a bit overwhelmed, and we would like to
  contribute it in the future (gue rivero will help us with Gerrit).

  Still, if anybody wants to test it in stable/diablo, we are more than
  open to help him to use it.

   Hello folks,

   I was wondering if anyone has tried setting up nova-volume on NFS
   backend without making any changes to nova-volume code?

   There is a Xen Storage Manager Volume driver that can support NFS, but I
   am looking for a non-Xen solution.
