Citrix Virtual Apps and Desktops SDK


Locks a VM.


Lock-ProvVM [-VMID] <String[]> -ProvisioningSchemeName <String> [-Tag <String>] [-LoggingId <Guid>] [-BearerToken <String>] [-TraceParent <String>] [-TraceState <String>] [-VirtualSiteId <String>] [-AdminAddress <String>] [<CommonParameters>]

Lock-ProvVM [-VMID] <String[]> -ProvisioningSchemeUid <Guid> [-Tag <String>] [-LoggingId <Guid>] [-BearerToken <String>] [-TraceParent <String>] [-TraceState <String>] [-VirtualSiteId <String>] [-AdminAddress <String>] [<CommonParameters>]

Detailed Description

Provides the ability to ‘lock’ a virtual machine with a tag string. This stops other commands from being able to remove the virtual machine without unlocking the VM first. This is to enable consumers of the virtual machines to indicate that the VM is being used.


Name Description Required? Pipeline Input Default Value
VMID The virtual machine Id (hypervisor context). true true (ByPropertyName)  
ProvisioningSchemeName The name of the provisioning scheme. true true (ByPropertyName)  
ProvisioningSchemeUid The unique identifier of the provisioning scheme. true false  
Tag The string to be held against the VM being locked. 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 Specifies the address of a XenDesktop controller that the PowerShell snap-in connects 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 'Vmid' And 'Provisioningschemename' To Lock-Provvm
