Known issues

The following issues are known at this release:

  • If Asynchronous I/O is selected for the virtual disk in environments using a VDA before version 2006, persistence of VDA metadata is lost. This includes updates to the Delivery Controller. [PMCS-11355]

  • A published image can crash when booting earlier versions of Citrix App Layering. [UNI-79222]

Previously reported issues

The following issues were reported in previous Citrix Provisioning releases and are applicable to the current release:

  • The Citrix Virtual Apps and Desktops Setup Wizard creates targets then boots them to format the cache drive. This process occurs quickly. Sometimes, a VDA reaches a state where it fails to shut down correctly. This process occurs because the VDA is initializing while the Citrix Provisioning Service and the provisioned device service simultaneously finish formatting the cache drive, then shuts down. To resolve this issue:
  1. In the virtual disk registry key, HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ProvisioningServices, create a DWORD called RebootDelaySec.
  2. Set a value, delay-to-shutdown, in seconds using a decimal value. [HDX-14474]
  • Virtual disk update schedule time cannot be applied after modifying it. It functions until you reboot the Citrix SOAP service. [PVS-4349]

  • Running Add-PvsDeviceToDomain without specifying a parameter adds all targets in every site to the computer’s container in Active Directory.

  • When importing VHDX files that you published from App Layering to the provisioned disk store, the operation mistakenly reports that you are using an invalid disk. You can eliminate this error by changing the period (.) characters in the published file name’s date and time. A valid file name contains only one period for the VHDX file name extension. [UNI-75902]

  • When using the Citrix Provisioning Setup Wizard to create VMs on a XenServer host while specifying 1 vCPU, the VM is created with 1 vCPU and a topology of 2 cores per socket. Creating VMs in this fashion prevents the VM from booting, while displaying the following error message in XenCenter: “The value ‘VCPU_max must be a multiple of this field’ is invalid for field platforms:cores-per-socket. As a result, XenCenter fails to boot the VM because the topology and vCPU configuration are incompatible. [#PVS-1126]

  • When using the Citrix Virtual Apps and Desktops Setup Wizard, the default VDA level is 7_9 even though there is a 7_20 VDA level. This behavior is the same in the Machine Creation Wizard in Studio. Also, the VDA level 7_20 in Citrix Virtual Apps and Desktops Setup Wizard is the same as the VDA level in Studio version 1811.

  • UEFI target devices do not support the List local hard disk in boot menu option. If you select this option in the boot menu, the system does not boot to hard disk for UEFI target devices. Instead, the system shows the boot menu again after timing out.

  • Before upgrading from version 7.17 to this version of Citrix Provisioning, you must manually uninstall CDF on the Provisioning Server, Console, and target devices.

Citrix Cloud

When using the Citrix Cloud feature, consider the following:

  • To install the remote PowerShell SDK on the Provisioning server, you must uninstall the 5 Citrix Virtual Apps and Desktop snap-ins from the server, then install the remote PowerShell SDK.

  • Once a Console is installed with the remote PowerShell SDK and is used for provisioning, it no longer functions with on-premises Citrix Virtual Apps and Desktops.

  • In the Citrix Virtual Apps and Desktops Setup Wizard, enter the IP address for the Citrix Cloud Connector when it prompts for the Citrix Virtual Apps and Desktops Controller Address.

  • In the Provisioning Console, the Citrix Virtual Apps and Desktops Setup Wizard cannot be used to connect twice in a row. Once the Wizard tries to connect to the Cloud Delivery controller once, regardless of connection success or failure, you must exit and close the Provisioning Console.

  • The MCS I/O driver causes a system to crash. To resolve this issue, Citrix recommends disabling the driver in Studio. [#PMCS-2941]
