Or at least provide a way to specify an external UUID for the instance, and can retrieve the instance through the external UUID which may be linked to external system's object.<br>

<p class="MsoNormal"><span lang="EN-US"><br>
Hello<br>
<br>
I would like to be able to specify the UUID of an instance when I create<br>
it. I found this discussion about this matter:<br>
<a href="https://lists.launchpad.net/openstack/msg22387.html" target="_blank">https://lists.launchpad.net/openstack/msg22387.html</a><br>
but I could not find any blueprint, anyway I understood this<br>
modification should not comport any particular issue.<br>
<br>
Would it be acceptable to pass the uuid as metadata, or should I instead<br>
modify the api if I want to set the UUID from the novaclient?<br>
<br>
Best regards<br>
<br>
