Review comment:
I have no idea :)
I only re-worked the code, the logic here is the same as it was before. I
made sure everything was kept the same with test cases.
The result of this code is the same as the replaced one. The difference is
that I am not using those if/if/if/if/if.....

> Unable to deploy VM instance from template if template spin from linked clone

> Key: CLOUDSTACK-9025
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9025
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: XenServer
> Affects Versions: 4.5.2
> Environment: XenServer 6.5
> Reporter: Anshul Gangwar
> Assignee: Anshul Gangwar
> Priority: Critical
> Fix For: 4.6.0
>
>
> As default, CloudStack create linked clone snapshot for VM instance . When we
> take a snapshot for the VM, and create a template based on such snapshot,
> CloudStack only download incremental VHD as template file, as a result, the
> VM instance fail to deploy as it is incomplete.
