How to Solve VirtualBox NS_ERROR_FAILURE Errors

If you’re a VirtualBox user, you may have already had the bad luck of running into an NS_ERROR_FAILURE (0x80004005).

Worry no more, our experts are here to help. This generic error is usually due to a failure to open a session for a virtual machine. Let’s take a look at some of the common causes and fixes to get our virtual machine up and running again.

Incompatible VirtualBox Extensions

If the VirtualBox extensions installed are not compatible with our current VirtualBox version, we are likely to run into the error message.

We can fix this by installing the correct extension pack version for our current VirtualBox version. For example, if we have VirtualBox 6.0.14, download the 6.0.14 extension pack.

Also, upgrade to a newer version of VirtualBox. It should be compatible with the extension pack we want to install.

Outdated/Corrupted VirtualBox Versions

Did you know that VirtualBox’s outdated or corrupted version can trigger this error?

In this case, we have to remove the current version to eliminate corrupted files. Then, reboot the system for the changes to take effect.

After that, download and install the latest stable release of VirtualBox.

Alternatively, we can try reverting to a previously stable version if the latest version doesn’t resolve the issue.

Graphics Driver Issues

Sometimes, problems with the graphics driver on the host system can lead to this error.

Try these troubleshooting tips to resolve this error:

• Check system logs for errors and update the graphics driver.
• Then, use a tool like Display Driver Uninstaller (DDU) to completely remove the existing driver.
• Next, download and install the latest driver from the manufacturer’s website.
• If issues persist, try using a previous driver version.

Incorrect Virtual Machine Configuration

Did you know that misconfigurations or unusual settings in the VM can prevent it from opening properly?

We can fix this by making sure all settings are correct and there are no unusual configurations.

System Cleanup

In some cases, corrupted files or configurations in the VirtualBox installation.

This is fixed by uninstalling and then reinstalling VirtualBox and its extensions to clear out corrupted files.

Host System Updates

Outdated host system updates may also cause compatibility issues.

So, make sure the host system is up-to-date. In some cases, host updates can resolve compatibility issues. Here are some ways to resolve these issues:

• Run Windows Update Troubleshooter:

  Go to Settings > Update & Security > Troubleshoot > Windows Update. Now, we can run the Windows Update troubleshooter to identify as well as fix issues related to Windows Update.
• Check for Windows Updates:

  Install any pending updates via Settings > Update & Security > Windows Update > Check for updates.
• Pause Windows Update:

  Temporarily pause updates to reduce network usage (Settings > Update & Security > Windows Update > Pause for 1 week).
• Disable BITS:

  Go to Services > Background Intelligent Transfer Service > Properties > Startup type > Disabled > Apply > OK.
• Scan for Malware:

  Run a full scan with Windows Defender.
• Reset Network Settings:

  Go to Settings > Network & Internet > Status > Network reset > Reset now.

User Permissions

Furthermore, not being part of the `vboxusers` group can restrict VirtualBox functionality.

So, run the command `sudo /etc/init.d/vboxdrv setup` tp fix the issue.
