Detailed Description

Lets you create a new provisioning scheme. The creation process makes a copy of the hard disk attached to a virtual machine snapshot or VM template and stores it in every storage location that the hosting unit referenced by the provisioning scheme defines. This is a long-running task and typically takes several minutes to complete (depending on the size of the hard disk that is being copied and the number of snapshots that the hard disk consists of).

A snapshot or VM template must be used rather than a VM, so that the content of the hard disk for the provisioning scheme can be easily determined.

Because the snapshot or VM template are specified using a path into the Citrix Host Service PowerShell Provider, the Citrix Host Service PowerShell snap-in must also be loaded for this cmdlet to be used.

This cmdlet requires information to be provided that is retrieved using other snap-ins that form part of the Citrix Machine Creation Services: Hosting Unit Service Snapin The snap-in that provides information about the hypervisors. AD Identity Service Snapin The snap-in that provides information about the identity pools.

The provisioning scheme is a collection of all of the data that is required to form a template against which virtual machines can be created. It therefore requires the following: Hosting Unit A reference to an item defined in the Host Service that defines the hypervisor, the network, and the storage to be used. Identity Pool A reference to the collection of Active Directory accounts that is used for virtual machines created from the provisioning scheme.

## Notes Only one long-running task for each provisioning scheme can be processed at a time.
In case of failure, the following errors can result.
Error Codes
-----------
JobCreationFailed
The requested task could not be started.
DatabaseError
An error occurred in the service while attempting a database operation.
DatabaseNotConfigured
The operation could not be completed because the database for the service is not configured.
ServiceStatusInvalidDb
An error occurred in the service while attempting a database operation. Communication with the database failed for
for various reasons.
MachineCreationServiceDoesNotSupportPersonalDisk
The service instance being used has not been upgraded to support the personal vDisk feature.
DatabaseMissingCapabilites
The database supporting the service instance being used has not been upgraded to support the personal vDisk feature.
CommunicationError
An error occurred while communicating with the service.
InvalidParameterCombination
Both PurgeJobOnSuccess and RunAsynchronously were specified. When running asynchronously, the cmdlet terminates before the job does, so it cannot clean up the completed job.
PermissionDenied
The user does not have administrative rights to perform this operation.
ConfigurationLoggingError
The operation could not be performed because of a configuration logging error.
ScopeNotFound
One or more of the scopes nominated for the new provisioning scheme do not exist.
WorkflowHostUnavailable
The task could not be started because the database connection is inactive.
ExceptionThrown
An unexpected error occurred. To locate more details, see the Windows event logs on the controller being used, or examine the XenDesktop logs. VhdParametersMustBeSupplied
When parameter VhdTemplateSource or VhdResultDestination is supplied, both parameters are required to be supplied. ServiceDoesNotSupportFullDiskClone
The full disk clone parameter is being used when the service does not support the full disk clone feature. Upgrade the service or remove the parameter. FullDiskCloneDoesNotSupportCleanOnBootVMs
The full disk clone functionality is applicable to dedicated provisioned machines only. FullDiskCloneDoesNotSupportPvdVMs
The full disk clone functionality is only applicable to dedicated provisioned machines that do not use Personal VDisks.
The cmdlet is associated with a task of type NewProvisioningScheme, and while active will move through the following operations (CurrentOperation field)
