Microsoft and Oracle resolve Windows 11 compatibility issues with VirtualBox

You might be unable to start Virtual machines (VMs) and you might receive an error due to a compatibility issue between VirtualBox and Windows 11 when Hyper-V or Windows Hypervisor is installed. This compatibility issue was placed in the Windows 11 Health Dashboard that was added on October 4, 2021. By March 11, 2022, Microsoft added a new note indicating that this problem has been solved, that is, the compatibility problem will be solved after the VirtualBox update.

Windows 11 Insider Preview Build 22518

When Microsoft Hyper-V/Windows Hypervisor is installed, a compatibility error occurs in the VirtualBox virtual machine, which prevents it from booting normally. Therefore, based on experience considerations, Microsoft directly prevents users who install this virtual machine from upgrading Windows 11 until Oracle fixes the problem. Microsoft explains: To safeguard your upgrade experience, we have applied a compatibility hold on these devices from installing or being offered Windows 11. If your organization is using Update Compliance, the safeguard ID is 35004082.”

Solutions to this problem include waiting for Oracle to release a new version to fix compatibility issues. At present, Oracle has released a new version to fix the problem. Microsoft adds: “Oracle has resolved this issue in VirtualBox 6.1.28 and later. To remove the safeguard hold on your device, you will need to update to VirtualBox 6.1.28 or later. Please note, if there are no other safeguards that affect your device, it can take up to 48 hours before the update to Windows 11, version 21H2 is offered.”
