Installing VMware Tools 5.1/5.5 on a Windows virtual machine reports Unity warnings in Windows Event logs (2038263)

轉載至 https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2038263

Symptoms

• After installing VMware Tools 5.1/5.5 on a Windows virtual machine, the Windows Application Event log of the guest operating system reports warnings.
• You see warnings similar to:

[ warning] [vmusr:vmusr] vmware::tools::UnityPBRPCServer::Start: Failed to register with the host! [ warning] [vmusr:vmtoolsd] Failed registration of app type 2 (Signals) from plugin unity.
[ warning] [vmusr:vmusr] Error in the RPC receive loop: RpcIn: Unable to send. 
[ warning] [vmusr:vmusr] socket count not create new socket, error 10047: An address incompatible with the requested protocol was used

[ warning] [vmusr:vmusr] Channel restart failed [1]

Cause

These warnings are related to the Unity feature of VMware Tools for Fusion/Workstation.

The Unity feature is not used by ESXi and therefore reports these warnings.

Resolution

This issue is resolved in:

•  ESXi 5.1 Update 2, available at VMware Downloads. For more information, see the VMware ESXi 5.1 Update 2 Release Note. 
• ESXi 5.5 Update 2, available at VMware Downloads. For more information, see the VMware ESXi 5.5 Update 2 Release Note.  

To resolve this issue, install the VMware Tools packaged with ESXi 5.1 Update 2 or ESXi 5.5 Update 2 on the affected virtual machines.

To work around this issue, use one of these methods.

Method 1: Disable Protocol Buffer Remote Procedure Call (PBRPC)

1. Open the tools.conf file of the guest operating system using a text editor.
   
   This file is located at:
   
   
   • Windows Vista, Windows 7, Windows Server 2008 and 2012:
     
     C:\ProgramData\VMware\VMware Tools\
   • Windows XP and Windows Server 2000/2003:
     
     C:\Documents and Settings\All Users\Application Data\VMware\VMware Tools\
2. In the tools.conf file, locate the line with the comment [unity] and change the Pbrpc.enable value from true to false.
   
   For example:
   
   [unity]
Pbrpc.enable=false
3. Restart the VMware Tools service.

Notes:

• If the tools.conf file does not exist, create a new file and use the content given above.
• Ensure to edit this file as an administrator.
• The Application Data/ProgramData folder is usually hidden. Ensure that hidden files are viewable.

Method 2: Delete the Unity plug-in

1. In the guest operating system, navigate to:
   
   C:\Program Files\VMware\VMware Tools\plugins\vmusr
2. Delete the Unity.dll file.
   
   Note: You may have to stop VMware Tools and end the vmtoolsd.exe process before deleting the file.
3. Restart the VMware Tools service.

Note: After removing the Unity Plug-in, you may see errors about it missing. To suppress these false errors, see Upgrading to VMware Tools 5.1 causes log spew with the message: Error in the RPC receive loop: RpcIn: Unable to send (2036350).
