It is very useful, if the user plan to perform some risky operations in a VM. I am not quite sure if we can model it in Nova, and let the user to create snapshot chain via Nova api. Has it been discussed in design session or mail group? Anybody know that?<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Feb 25, 2014 at 6:40 PM, John Garbutt <span dir="ltr">

It depends if that can be modelled well with the current<br>
Nova/Cinder/Glance primitives.<br><br>
If you do boot from volume, and you see the volume snapshots, and they<br>
behave how cinder expects, and you can model that snapshot as an image<br>
in glance that you can boot new instances from, then maybe it would<br>
work just fine. But we need to take care not to bend the current API<br>
primitives too far out of place.<br><br>
I remember there being some talk about this at the last summit. How did that go?<br><br>
