Detailed Description

Provides the ability to update the hard disk image used to create virtual machines. If the provisioning scheme is a ‘CleanOnBoot’ type, then the next time that virtual machines are started, their hard disks are updated to this new image. Regardless of the ‘CleanOnBoot’ type, all new virtual machines created after this command will use this new hard disk image.

A background task will be created to remove the old hard disk copies. You can locate and monitor this task using the Get-ProvTask cmdlet.

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

As 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 to use this cmdlet.

The previous hard disk image path is stored into the history (see Get-ProvSchemeMasterVMImageHistory). The data stored in the history allows to do a rollback to revert to the previous hard disk image if required.


Name Description Required? Pipeline Input Default Value
ProvisioningSchemeName The name of the provisioning scheme to which the hard disk image should be updated. true true (ByPropertyName)  
MasterImageVM The path in the hosting unit provider to the VM snapshot or template that will be used. This identifies the hard disk to be used and the default values for the memory and processors. This must be a path to a Snapshot or Template item in the same hosting unit used by the provisioning scheme specified by ProvisioningSchemeName or ProvisioningSchemeUid. Valid paths are of the format      
XDHyp:\HostingUnits<HostingUnitName><path><VMName>.vm<SnapshotName>.snapshot XDHyp:\HostingUnits<HostingUnitName><path><TemplateName>.template true true (ByPropertyName)    
ProvisioningSchemeUid The unique identifier of the provisioning scheme to which the hard disk image should be updated. true false  
VhdTemplateSource A file path to a source VHD template to be used when performing application scanning during image preparation. The presence of this parameter in conjunction with VhdResultDestination implies that application scanning is to be performed false false  
VhdResultDestination A file path (including file name) where the VHD disk file containing the results of application scanning should be written. false false  
AppScanResultsFile File name to which the results of application scanning should be written. false false  
FunctionalLevel The FunctionalLevel of the VDA installed on the given MasterImageVM. false false  
MasterImageNote The note of the master image. false false  
RunAsynchronously Indicates whether the cmdlet should return before it completes. If specified, the command returns an identifier for the task that was created. You can monitor this task using the get-ProvTask cmdlet. false false false
PurgeJobOnSuccess Indicates that the task history will be removed from the database once the task completes. This cannot be specified for tasks that run asynchronously. false false false
DoNotStoreOldImage Indicates that the current image should not be added to the image history list for the provisioning scheme. This is useful when rolling back to a previous image. false false  
LoggingId Specifies the identifier of the high-level operation this cmdlet call forms a part of. Citrix Studio and Director typically create high-level operations. PowerShell scripts can also wrap a series of cmdlet calls in a high-level operation by way of the Start-LogHighLevelOperation and Stop-LogHighLevelOperation cmdlets. false false  
BearerToken Specifies the bearer token assigned to the calling user false false  
TraceParent Specifies the trace parent assigned for internal diagnostic tracing use false false  
TraceState Specifies the trace state assigned for internal diagnostic tracing user false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  
AdminAddress The address of a Citrix Virtual Apps and Desktops controller the PowerShell snap-in will connect to. You can provide this as a host name or an IP address. false false Localhost. Once a value is provided by any cmdlet, this value becomes the default.

Input Type


You can pipe an object containing a parameter called ‘ProvisioningSchemeName’ to Publish-ProvMasterVMImage.

Return Values


When “RunAsynchronously” is specified, this identifier is returned to provide the task identifier.


Only one long-running task per provisioning scheme can be processed at any one time. In the case of failure, the following errors can result.

  • 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.

  • WorkflowHostUnavailable: The task could not be started because the database connection is inactive.

  • CommunicationError: An error occurred while communicating with the service.

  • 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.

  • ExceptionThrown: An unexpected error occurred.

For more details, see the Windows event logs on the controller being used or Citrix Virtual Apps and Desktops logs.

The cmdlet is associated with a task of type PublishImage, and while active will move through the following operations (CurrentOperation field) ValidatingInputs ConsolidatingMasterImage PreparingMasterImage ReplicatingMasterImage CommittingScheme
