<div><br></div><div>There is a dirty hack that you could perform for that. What you could do is (depends on your storage backend):</div><div><br></div><div>- detach the volume from project A</div><div>- create a dummy volume on project B</div>
<div>- make pointed the volume from project A to the dummy in project B </div><div>- delete the volume from project A</div><div><br></div><div>If you use Ceph RBD it's really easy for example. </div><div><br></div><div>
For the rest I don't know.</div><div class="gmail_extra">

<p dir="ltr">Hi,</p>
<p dir="ltr">What I will do to achieve what you want:</p>
<p dir="ltr">_ take a snapshot of your instance<br>
_ export the snapshot from wherever it's stored (filesystem for instance)<br>
_ import it to Glance, make the image to public or assign it to the tenant (not 100% sure if the latest is possible though...)<br>
_ run a new vm with the based image previously created</p>
<p dir="ltr">Some steps could be avoided like step 2 and 3. You could use the admin user to snapshot and then run the snapshot from the other tenan. However it's NOT recommended.</p>
<p dir="ltr">Cheers.</p>
