You can configure virtual machine runtime settings, such as logging, disabling acceleration, record debugging information, enabling VMI paravirtualization, and virtualized Memory Management Unit (MMU) settings.


In the Commands section of the virtual machine’s Summary tab, click Configure VM.


Click the Advanced tab.


In the Settings section, select any of the options.



Record runtime information

Collects debugging and performance information. You can use this information to troubleshoot problems.

Enable logging

Enables event logging.

Disable acceleration

Disables acceleration in the virtual machine. You might want to temporarily disable acceleration if you are installing or starting a program in a virtual machine and the program stalls, fails, or reports that it is running under a debugger.

Disabling acceleration slows virtual machine performance, so when you no longer have a problem, deselect Disable acceleration.

Support VMI Paravirtualization

If you have a VMware VMI 3.0-enabled kernel in a Linux guest, VMI paravirtualization improves virtual machine performance.

For more information about paravirtualization, see

Available VMI-enabled kernels include Ubuntu 7.04 (Feisty) or later.

Use the standard image for 32-bit Intel x86 systems. VMI currently supports only 32-bit guests.


Only hardware version 7.0 virtual machines support VMI.


In the Virtualized MMU section, select an option.

Recent CPUs can virtualize the MMU. Virtualizing the MMU generally improves virtual machine performance. In some instances, it might be preferable not to virtualize the MMU.


Click OK.

The virtual machine runtime settings are reconfigured.
