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?
