You can temporarily disable acceleration to allow a virtual machine to successfully run or install software.

In rare instances, you might find that when you install or run software in a virtual machine, the virtual machine appears to stop responding. Generally, the problem occurs early in the program’s execution. Often, you can get past the problem by temporarily disabling acceleration in the virtual machine.

Disabling acceleration slows down virtual machine performance. You must enable acceleration after the program stops encountering problems to run the program with acceleration.

You can enable and disable acceleration when the virtual machine is running.


  1. In the vSphere Client inventory, right-click the virtual machine and select Edit Settings.
  2. Click the Options tab and under Advanced select General.
  3. In the Settings pane, select Disable acceleration.
  4. Click OK to save your changes.
