VirtualBox Guru Meditation error is a critical issue that affects users of VirtualBox software, particularly those running Linux Ubuntu 22.04. This error occurs when the VirtualBox machine execution is stopped due to an unhandled exception in the VCPU (Virtual CPU) emulation layer. The error message 'VCPU0: Guru Meditation -37 (VERR_NOT_SUPPORTED)' indicates a hardware-related issue with the virtualization extension. This error can be frustrating as it prevents users from running their virtual machines, and deleting and reinstalling VirtualBox does not resolve the problem.

This error can occur due to various reasons such as incorrect configuration of the virtualization extension or a bug in the VirtualBox software.
