Initialization issue with VDI clones created with Unidesk

Initialization issue with VDI clones created with Unidesk

Version

v7.x

 

Issue

When using Unidesk application to create VDI clone machines, the clones will not successfully complete initialization and show 'Up to Date' in the Bit9 Console.

 

Symptoms

The clones will show up in the console as  "unprotected - reboot required" and might get stuck at 99% initialization, but never complete the process.

 

 

Cause

Some VM and machine cloning methods generate new volume ID's. This invalidates the GUID based paths in our registry settings and causes other problems, such as the driver not recognizing Parity service as a Bit9 process.

 

Solution

To fix this, simply clear the following two registry values as part of your cloning process. On next boot, the Parity driver will automatically recalculate the correct volume GUID and installation path. If Bit9 is part of the gold base image, that is the place to make this change.

 

Registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ParityDriver\Parameters

Values

ParityAgentInstallPath

ParityAgentDataPath

 

The Parity driver, the Parity agent service and the tamper protection must be off in order to alter the registry value. It might be necessary to attempt this change in  If your VM build process can set registry values before the driver is running (possibly as an off-line process), that should be sufficient. If you need to turn off tamper protection:

In an elevated command prompt:

dascli password <CLI_password>

dascli tamperprotect 0

net stop parity

fltmc unload parity driver

<change registry settings>

<save Golden Image without rebooting>

 

Newly deployed clones should successfully start the Bit9 agent and have the correct registry keys to register with the Bit9 console and finish initialization successfully.
