See the VirualBox Change Log for more information on this. If VirtualBox v6.1.4 (or later) is installed alongside Microsoft Hyper-V, VMs will not run with optimum performance. This doesn’t affect the state of existing VMs, whether they are running or not: Macrium viBoot will be restarted after changing Hypervisor mode. Please run 'bcdedit / set hypervisorlaunchtype off' after disabling Hyper-V feature from 'Turn Windows features on or off' Microsoft Hyper-V feature must be disabled for VirtualBox 6.0.xx to function. Note: VirtualBox less than v6.1.4 cannot be run on Windows where Microsoft Hyper-V service is running. ViBoot can be switched between Hyper-V and VirtualBox mode using the ‘Tools’ menu: In addition, VirtualBox includes a USB pass-through virtual device that enables USB drives, including flash, to be accessible from inside the Virtual Machine.

VirtualBox v6.1.4 can be run on Windows 8/Server 2012 R2 and later regardless of whether the native OS includes a Windows Hypervisor layer.

VirtualBox provides an alternative to Microsoft Hyper-V for instant image virtualization. We’ve added direct support for Oracle VirtualBox by implementing.
