VirtualBox 3.1 Error in Oracle

Asked By 0 points N/A Posted on -

My problem is related to Oracle. I have an Oracle Virtual Memory in my VirtualBox 3.1 and I had it for quite some time already. I think it sends a dialog box everyday asking me to install some updates for the software but I did not try to install anything. Now I was tempted to install because I see the same dialog box every time I run Oracle. I guess I have installed the latest updates and version of it. The installation was very smooth and it finished without any error. But when I started running it for the first time after its complete installation, I got this error message saying: Unknown error creating VM (VERR_ NOT_FOUND). I was disappointed to see that. I have attached the error message below:

VirtualBox - Error Failed to open a session for the virtual machine Implementation of the USB 2.0 controller not found!

VirtualBox – Error

Failed to open a session for the virtual machine racnode1

Implementation of the USB 2.0 controller not found!

Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix the problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).

Unknown error creating VM (VERR_NOT_FOUND).

VirtualBox 3.1 Error in Oracle


That is a bug in the application that is causing to malfunction, but the good thing is that it can be easily fixed. You will just need to do the following:

  • On your machine, you will need to locate your machine xml files, if you are using windows operating system then they can be found at C:Users<your username>.VirtualBoxMachines<your machine>
  • You will need to stop the VirtualBox Manager as follows:

    • You will need to open the file and locate the line below and then set enabledEhci to false.

 <USB Controller enabled="true" enabledEhci="false"/>

  • Once you have done that, you can start the VirtualBox Manager, and then resume the virtual machine.
