Solution

Summary and Symptom

Non-hyperthreading based multicore processor systems incorrectly report the availablity of hyperthreading. This fix correctly reports the status for Hyperthreading supported on multicore processors.
 
Symptom:  The following symptoms might be displayed:
  • On the service console

Running the esxcfg-info –w command on non-hyperthreading based multicore processor systems generates the following output:

|----Hyperthreading Active....................................false
|----Hyperthreading Supported.................................false
|----Hyperthreading Enabled...................................true

  • On the VI Client   
In the Configuration tab, click Processors. Hyperthreading is displayed as N/A. 


Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table, above.

Patch Download and Installation
