Oracle VirtualBox, Failed to open a session

December 7, 2019 30 sec read

I like to play with computers. So Oracle’s VirtualBox is handy to install different operating systems (Linux, Windows, Mac etc) and try them. But recently when I tried to open any virtual machines I got the following error:

Failed to open a session for the virtual machine Ubuntu18. Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED). Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I searched and tried different solutions such as running as administrator, reinstalling VirtualBox, uncheck Hyper-V in the “Turn Windows Feature On/OFF” setting etc, but none works. Eventually the following method works:

Open a command line window (run as Administrator), then run the following command:
bcdedit /set hypervisorlaunchtype off
Then reboot the host computer.

It works! Thank the post in this page.
