Windows 10 1903 | Oracle VirtualBox virtual machines will not start/open

Hello guys

This is a quick post towards one of the issues I faced once after enabling Windows Sandbox feature that was made available with Windows 10 1903. As Sandbox feature utilizes Hyper-V (regardless whether you have enabled it or not).

Once Sandbox feature enabled, Oracle VirtualBox 6.0.x fails to launch the Virtual Machines.

Although VirtualBox 6.0.x are supposed to support Hyper-V for acceleration, my attempts were futile, forcing me to disable the Sandbox feature, enter BIOS and browse through the virtualization settings.

I can’t say what has resolved the issues. I disabled Sandbox, restarted the box, was unable to launch the Virtual Machines.

Restarted the laptop, entered BIOS and insured that the virtualization was turned on & tried to launch the Virtual Machines and they opened.

So give it a try, if you are stuck with the following error while trying to open a Virtual Machine!

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

    1. Glad to know that you got around it. VirtualBox started to have many issues, especially display related (nvidia) recently and they were being persistent through builds. Thanks for stopping by
