PAUSED. In a paused state, the state of the server is stored in RAM. A paused server continues to run in frozen state.
REBOOT. The server is in a soft reboot state. A reboot command was passed to the operating system.
REBUILD. The server is currently being rebuilt from an image.
RESCUED. The server is in rescue mode. A rescue image is running with the original server image attached.
RESIZED. Server is performing the differential copy of data that changed during its initial copy. Server is down for this stage.
REVERT_RESIZE. The resize or migration of a server failed for some reason. The destination server is being cleaned up and the original source server is restarting.
SOFT_DELETED. The server is marked as deleted but the disk images are still available to restore.
STOPPED. The server is powered off and the disk image still persists.
SUSPENDED. The server is suspended, either by request or necessity. This status appears for only the XenServer/XCP, KVM, and ESXi hypervisors. Administrative users can suspend an instance if it is infrequently used or to perform system maintenance. When you suspend an instance, its VM state is stored on disk, all memory is written to disk, and the virtual machine is stopped. Suspending an instance is similar to placing a device in hibernation; memory and vCPUs become available to create other instances.

Basic service, the first part (variables) include the description of the service.
Remember to fill all variables needed, but at least you must define:
* typeName

* typeDescription
* iconFile (defaults to service.png)
* publicationType, type of publication in case it needs publication.
If this is not provided, core will assume that the service do not
needs publishing.
* deployedType, type of deployed user service. Do not forget this!!!
The rest of them can be ommited, but its recommended that you fill all
