Systemvm template:
primary storage is mounted in the host (xenserver)
Secondary storage is mounted in the ssvm
Systemvm template id is : 1
User vm template id is : 13
template_store_ref: It will trigger and track the template download job into the secondary storage. By default systemvm template is there on the secondary storage. No job is needed. For the user vm template requires a job to download from the URL to the secondary storage.
template_spool_ref: It will have the downloaded template paths in primary storage. Also xenserver vdi path.
storage_pool: It contains the primary storages added in the cloudstack.
CopyCommand: It will copy the template from the secondary storage to primary storage.
