Hi,
This is something that would be nice to add as an extension. At the moment it is not part of our near term development plans. It would be nice to engage the community to discuss and see how this can be exposed correctly using the Nova API's. It may be something worthwhile discussing at the up and coming summit.
Thanks
Gary

Subject: Re: [openstack-dev] [Nova][VMWare] VMware VM snapshot

What I mean is the snapshot of vsphere, which is describe in this page --> http://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.vm_admin.doc_50%2FGUID-CA948C69-7F58-4519-AEB1-739545EA94E5.html

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?

It depends if that can be modelled well with the current
Nova/Cinder/Glance primitives.

If you do boot from volume, and you see the volume snapshots, and they
behave how cinder expects, and you can model that snapshot as an image
in glance that you can boot new instances from, then maybe it would
work just fine. But we need to take care not to bend the current API
primitives too far out of place.

I remember there being some talk about this at the last summit. How did that go?
