Hmm.... The cinder volumes dont automount either. /dev/vdx shows up, but you have to format/mount it yourself.<br>
<br>
Maybe both teams could share a common solution? Im guessing it will have to be an agent...<br>
<br>
Thanks,<br>

<div>Hi,<br>
</div>
Have we considered cloud-init and qemu guest agent, I remember there was some discussion around this<br>
</div>
in the prev summit, but i couldn't find any etherpad/notes on that.<br>
<br>
</div>
<div>I had one more question in this regards. Is it possible to do some kind of VM hotplug add operation as part of manila<br>
</div>
<div>access allow which will cause the VM to see a new drive with a pre-specified label and a client inside the VM will<br>
</div>
<div>mount it as part of the udev/uevent ? <br>
</div>
</div>

Thanks, Luis, I agree with your assessment that one good way to solve this<br>
issue is a publisher-subscriber model. The publisher would be Manila,<br>
using zeroconf or AMQP or Zaqar (the one Iım investigating now). The<br>
subscriber would be a lightweight agent running on the client that listens<br>
for share availability events and handles the mounts. One open question<br>
is whether Manila needs to store a record of client mounts, without which<br>
it could not influence the mount paths on each client.<br>
