UPD disk does not attach to VMs when a DVD drive is configured in Windows Server 2016

Applies to: Windows Server 2016


Consider the following scenario:

  • You set up a virtual desktop infrastructure (VDI) environment that's based on a Generation 2 virtual machine (VM) in Windows Server 2016.

  • The VM has a DVD drive that's configured in a location next to the hard disk drives on the SCSI controller. Generally, this is "location 2."

  • You configure the VDI environment to use a User Profile Disk (UPD).

  • You log on to the desktop.

In this scenario, the profile disk does not attach to the VM. Therefore, a temporary user profile is incorrectly used. Also, the following event is logged in the event log:

Log Name:      Microsoft-Windows-TerminalServices-TSV-VmHostAgent/OperationalSource:        Microsoft-Windows-TerminalServices-TSV-VmHostAgentDate:          Event ID:      8479Task Category: ConfigurationLevel:         WarningKeywords:      User:          NETWORK SERVICEComputer:      Description:Remote Desktop Virtualization Host could not run the Hyper-V WMI job.Error description: '' failed to add device 'Synthetic Disk Drive'. (Virtual machine ID )'': Cannot attach storage media to the controller because the specified location is in use. (Virtual machine ID )See also Hyper-V event logsHresult: 0x80078007



To work around this issue, remove the DVD drive or reconfigure it to another location.
