> When I create more than one templates from an existing virtual machine, the second and
the subsequent template is created the same as first one. 
> It doesn't occur in the case of using NFS secondary storage. So I guess this is the S3
provider specific issue.
> This could reproduce as following procedure.
> (1) create a virtual machine (name "foo" tentatively), and modify some files on ROOT
volume of "foo".
> (2) stop "foo". and create template "template-foo.1" from ROOT volume of "foo".
> (3) reboot (not re-create) "foo", and modify some files on ROOT volume again.
> (4) stop "foo". and create template "template-foo.2" from ROOT volume of "foo".
> I expect that template-foo.2 keeps (3)'s changes. But template-foo.2 is the same as template-foo.1.
(3)'s changes are not recorded.
> As of (4), CloudStack outputs the following DEBUG message to cloudstack-management.log.
> 2014-08-07 19:23:20,094 DEBUG [o.a.c.s.c.m.StorageCacheManagerImpl] (Job-Executor-58:ctx-b00fbe22
ctx-6339bae6) there is already one in the cache store
> When creating templates on NFS secondary storage environment, this message is not output.
> This issue also exists on CloudStack 4.2.1.
