Updating Devices in the New Virtual Machine
If when you created your new virtual machine, certain physical devices might no longer apply, you can deinstall them from your virtual machine. Removing or disabling software related to specific hardware that is no longer present in the virtual machine, such as hardware monitoring agents, improves the virtual machine performance.
To identify which devices are no longer physically installed on your virtual machine, use the Microsoft environment variable devmgr_show_nonpresent_devices.
1. From the command prompt, type:
set devmgr_show_nonpresent_devices = 1
2. Start the search. Type:
3. From the Device Manager, list the devices.
Select: View > Show hidden devices.
4. Deinstall the listed devices:
Select the device and uninstall it from the Device Manager.
For additional information, refer to Microsoft Knowledge Base articles 241257, 325539, and 269155.
If your virtual machine is configured with an SMP-compatible HAL (ACPI multiprocessor), but it only has one virtual CPU, use the Device Manager and change to an SMP-upgradeable HAL (ACPI uniprocessor). The helps prevents possible idling errors.
