      REPRO STEPS
      ==================
      1. Register a template A and specify property:
      Root disk controller: scsi
      NIC adapter type: E1000
      Keyboard type: us

      2. Create a vm instance from template A

      3. Take volume snapshot for vm instance

      4. Delete VM instance

      5. Switch to "Storage->Snapshots", convert snapshot to a template B

      6. Observe template B does not inherit property from template A, the table vm_template_details is empty

      EXPECTED BEHAVIOR
      ==================
      Template should inherit property from source template

      ACTUAL BEHAVIOR
      ==================
      Detail template property lost
