    @ProjectMoon : sounds good let me know of any more PoC code or further 
design.


> Make VM naming services injectable and in their own module
> ----------------------------------------------------------

>                 Key: CLOUDSTACK-9003
>                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9003
>             Project: CloudStack
>          Issue Type: Improvement
>      Security Level: Public(Anyone can view this level - this is the 
> default.) 
>            Reporter: Jeffrey Hair
>            Priority: Minor

> Proposal: Make the various classes/code that give VMs and other resources 
> hostnames, hypervisor guest names, and UUIDs into their classes as injectable 
> dependencies in their own module under the core or backend module.
> This proposal originally only concerned the VirtualMachineName class and can 
> be broken down into several parts:
> * Make the VirtualMachineName class an injectable dependency instead of being 
> full of static methods.
> * Refactor the generateHostName method in UserVmManagerImpl to be backed by 
> an injectable service which generates host names.
> * Move the UUIDManagerImpl from the core module to a new module (grouped with 
> the other 2 ideally).
> Rationale:
> * VirtualMachineName is one of the few remaining classes that has static 
> methods tangled like spaghetti throughout the code. This change will put it 
> in line with the rest of the management server codebase and opens the door to 
> extensibility. Which brings us to...
> * Extensibility: The ultimate goal of this feature is to provide 3rd party 
> developers the option of changing default instance/resource naming policies. 
> Currently this is possible in a very limited fashion with the instance.name 
> global setting, but this proposal makes it much more extensible.
> By moving the naming-related services (VirtualMachineName, UUIDManager, and 
> more as added/discovered) to their own module, the module can be excluded by 
> modules.properties and different ones substituted in. Alternatively, it could 
> use the adapter model that other classes use, and the user can configure 
> which adapters are active and also provide custom ones.
> A good use case for this functionality is using a different style naming to 
> emulate other cloud providers such as AWS (i-abc123) or GCE.
