Windows 10 - Failed to open session for the virtual machine error

Post by dalio »

Hello,

I recently upgraded my pc to Windows 10 and I am not able to run any VMs in VirtualBox. I use VBox version 5.0.32 (which used to work fine in Windows 7), but I get the error below when I try to start any VM:

Code: Select all

Failed to open session for the virtual machine
The virtual machine 'VM_name' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'D:\VBox_VMs\VM_name\Logs\VBoxHardening.log'.

Result Code: 	E_FAIL (0x80004005)
Component: 	MachineWrap
Interface: 	IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

The VBoxHardening.log has been attached.

Unfortunately, I cannot install any 5.1.x or later versions as this is causing the VM to run into the errors below:

Code: Select all

Uhhuh. NMI received for unknown reason 21.
Do you have a strange power saving mode enabled?
Dazed and confused, but trying to continue
Can you please advise how to resolve this issue?

Thanks.

You probably need to read the FAQ: Diagnosing VirtualBox Hardening Issues.
