There it says in the meantime "fixed in 6.1.28".

Oracle has documented the status of the conflict between Virtualbox and Hyper-V in ticket 20536 No VM will start on Windows 11 host. It was said at the time: Oracle is working on a solution and is expected to release a compatible version of VirtualBox in October 2021. Microsoft had imposed a compatibility lock that prevented these devices from installing Windows 11 or offering the OS as an upgrade on such Windows 10 machines. This was because Microsoft and Oracle had identified a compatibility issue between VirtualBox and Windows 11 when Hyper-V or Windows Hypervisor is installed.Īs a result, virtual machines (VMs) might not start and an error would be displayed. Using Virtualbox together with Hyper-V was not possible in Windows 11. I had pointed out the issue in the blog post Windows 11: Known issues (October 5, 2021).
