[one-users] deferred snapshots: when are they created?

[Stuart Longland]

Hi all,

I'm trying to rattle some bugs out of my storage driver on OpenNebula
4.4.  Right now I have (non-live) migration working, cloning and
deleting work, etc.

My progress is here: http://dev.opennebula.org/issues/2827

I've turned my attention to snapshotting.  I can do a "hot" snapshot,
that works, I see the VM pause momentarily while the snapshot is taken,
then everything resumes.

As for a deferred snapshot, I tell it to go ahead, then proceed to try
everything I can think of to make it take the snapshot.  Shut down,
power off, reboot, un-deploy, anything.  Nothing happens.  Clearly I
haven't hit upon the conditions that trigger a snapshot to take place.

What state is the snapshot supposed to be taken and under what conditions?

Regards,
