Answer by Akash Shah

Regarding your issue with VirtualBox and the "Blue screen of death" with error code 0x9F:


The error code 0x9F indicates a DRIVER_POWER_STATE_FAILURE, which typically occurs when there are issues with power management settings or drivers in Windows. Here are some steps you can take to resolve this issue:

  1. Update Drivers: Make sure all your system drivers are up to date, especially network and chipset drivers, as outdated drivers often cause this error.

  2. Check VirtualBox Version: Ensure you are using the latest version of VirtualBox. Sometimes, older versions may have compatibility issues with newer operating systems or updates.

  3. Adjust Power Settings: Go to the Control Panel > Power Options and set your power plan to Balanced or High Performance. Disable any advanced power-saving features for devices that do not need them.

  4. Disable Unnecessary Devices in VirtualBox: Sometimes, disabling unnecessary hardware acceleration features or virtual devices in your VirtualBox settings can help.

  5. Check for Conflicting Software: Some third-party software, especially anti-virus programs, can cause conflicts. Try disabling or uninstalling recently installed software to see if it resolves the problem.

  6. Check Event Viewer: Reviewing the Event Viewer for specific error messages can give more insight into what might be causing the power state issue.

If these steps do not resolve the problem, you may need to perform further diagnostics or consider seeking professional technical support.

Shortly after Faronics Deep Freeze, Oracle will discontinue its VirtualBox support by end of this year, and the software was being integrated into future versions of Windows as part of boot advanced feature for this system configuration options functionality.


The company said it would be officially transitioned to its more additional Windows features and the software will no longer receive any updates or a future versions of VirtualBox, and technical support would continue to use the VirtualBox feature by end of this year.

No, there is no portable version released by Oracle, but there is a safe fork of the VirtualBox development. You can download and customize it the way you want it since it allows pre-customization before actual deployment. The tool is developed to support latest releases of VirtualBox application.

Note: There is a guide on the front page that explains how to proceed.

This driver is installed and operated by VirtualBox. Most likely, you have not accepted the installation of the driver. Please perform a new installation of VirtualBox and when the installer prompts, please accept all the driver installation. Then it will work because that drivers were created to be compatible with operating systems where VirtualBox will be installed.

VirtualBox is a virtualization application which allows you to install multiple operating systems that can run inside your OS. The program does not make modifications to your system's integrity and functionality unless you choose the proper installation method (an actual partition drive instead of virtual hard disk). You can use the application however you want as long as you don't touch the partitions because things may get complicated if you do so.

To use host-only networking, you need to make sure that the option is selected for installation. This can be done when you're installing the application.

After this procedure, create a new virtual machine and access its Settings when you've finished creating it. Click the Network on the left, and select Host-Only Adapter. You can see in the image below as well.

Yes, there are extensions for VirtualBox, but they're not available for current version of VirtualBox. The Old Builds page provide a way to download these extensions. They're in .vbox-extpack file format. Double click the file you've downloaded from the OldBuilds page and VirtualBox will prompt you to install them. The extensions are used to increase VirtualBox functionality and they're created for:

  • The virtual USB 2.0 (EHCI) device;
  • The virtual USB 3.0 (xHCI) device;
  • VirtualBox Remote Desktop Protocol (VRDP) support;
  • Host webcam passthrough;
  • Intel PXE boot ROM.
  • Experimental support for PCI passthrough on Linux hosts;
  • Disk image encryption with AES algorithm;

Can VirtualBox create a bootable system? On a USB stick, for example.

A
Answer by Alex Urbach

No, you can't create a bootable system in VirtualBox. The application allows you to boot from a USB or a ISO, but it doesn't have the feature to create a bootable flash drive with the operating system. You will have to use another application to create a bootable USB with an operating system. For example, use Rufus or Unebootin to create a bootable USB and then assign it to the virtual machine created in Virtualbox.

What are guest additions for VirtualBox?

A
Answer by Alex Urbach

Guest Additions are a set of drivers targeted for installation when an operating system has been fully installed and working. These drivers are used to optimize the guest system for better performance and usability. To install them, start the virtual machine, then access Tools from the Virtualbox menu bar and select Install Guest Additions. You will see that a virtual CD drive will be populated with these. An autorun menu will start. Simply click Next, Next, etc. until it's finished. Reboot the guest system and you'll have 3D graphics support, better mouse integration, USB support, keyboard/touch support, etc.
