[SOLVED] VBOX_E_INVALID_OBJECT_STATE (0x80BB0007)

[abcdefgh]

I've solved the problem. It was actually easy (and logical if you accept the logic of Windows). I'm leaving this for the benefit of others.

Windows was launching VBox twice. I went to 'Windows Settings' > 'Apps' > 'Startup' and turned the duplicate 'VirtualBox Manager' launch to 'Off'. Why did Windows list 'VirtualBox Manager' twice? Who knows.

Version 6.1.12 r139181 (Qt5.6.2)
Host: Win10-1803
Guest: Linux Mint 18.3 Cinnamon 64-bit

When I start Windows, the following StartUp script runs:
"C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" c:\VMs\Mint18\Mint18.vbox
The VM launches, but I also get the following error:

Code: Select all

Failed to open a session for the virtual machine Mint18.

The machine 'Mint18' is already locked by a session (or being locked or unlocked).

Result Code: VBOX_E_INVALID_OBJECT_STATE (0x80BB0007)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

What I've tried:

1, I ran the command

• bcdedit /set hypervisorlaunchtype off

and restarted. It did not fix the problem.

2, I inspected 'Windows Features'.

• [_] Windows Hypervisor Platform

is not checked (i.e. is not enabled).

3, With VM shut down, 'Oracle VM VirtuBox Manager' > 'Mint18' > right-click:

• Discard Saved State...

is grayed out and cannot be selected.

4, 'Task Manager' > 'Performance' > 'CPU' shows

• Virtualization: Enabled

5, 'Windows Defender Security Center' > 'Device security' > 'Core isolation'

• Memory integrity is Off

6, I didn't alter Secure Boot because that seems too drastic to me.

7, I searched 'UserManual.pdf' for "VBOX_E_INVALID_OBJECT_STATE" and got no hits.

8, I searched 'UserManual.pdf' for "MachineWrap" and got no hits.

9, I searched 'UserManual.pdf' for "IMachine" and got 3 hits but nothing useful.

10.1, In order to get a fresh log, I shut down the VM, restarted it, and shut it down again.

10.2, I searched 'VBox.log' for "VBOX_E_INVALID_OBJECT_STATE" and got no hits.

10.3, I searched 'VBox.log' for "MachineWrap" and got no hits.

The topic is marked as solved, so what finally fixed it?

The OP edited his post and put a paragraph in bold at the beginning to say what the fix was. Yes, it's can be confusing when people edit their posts in that way. Better I think to add a follow up post.
