Review comment:
Yes, we only use secondary storage to build the template from snapshot. This
might not be applicable to managed store. But that's also available to all
hosts in zone so any random host in a zone will do.
Also we can delete volume without deleting its snapshot (backup). We only
delete VM snapshots when we delete VM.
Yes I meant using JPA queries.

> As default, CloudStack create linked clone snapshot for VM instance . When we

> CloudStack only download incremental VHD as template file, as a result, the
> VM instance fail to deploy as it is incomplete.
