The most common cause is that virtualization is either not enabled in the BIOS/UEFI settings or that the Hyper-V feature is disabled in Windows. Other potential issues include conflicts with Virtualization-Based Security (VBS) or problems with the WSL installation itself.
Solution 1: Enable Hardware Virtualization from BIOS
When users try to run Ubuntu in a VirtualBox without enabling Hardware Virtualization, the system causes multiple errors, such as audio performance issues and the WSL Register Distribution error. A virtual machine acts like a real computer, letting you use different operating systems and software on your device. Note: Make sure your device supports hardware virtualization. You can check if Virtualization is enabled under the Performance tab in the Task Manager.
Solution 2: Enable the Hyper-V Feature
Hyper-V enables administrators to make better use of their hardware by virtualizing multiple operating systems to run off the same physical server simultaneously. If it is not enabled, an error may occur while installing a Linux distribution to access via Windows.
Solution 3: Expose Virtualization Extensions & Change RAM Settings
Nested virtualization is a feature that allows you to run Hyper-V inside a Hyper-V virtual machine (VM). This helps run a Visual Studio phone emulator in a virtual machine or test configurations that ordinarily require several hosts. It has been reported that activating Nested Virtualization has worked as a solution for many users online.
