Comment 2 for bug 1191115

Hello Mark: thanks for response. So how do you differentiate between legitimate long running snapshots and a a snapshot the fails right away, how would you do this today? I think the only gap for glance is to allow errors to be reported, that was we can put image in a state that indicates something already happened. Of course nova virt drivers will need to then report to glance the errors during their error handling, but the would be outside the scope of glance.
