Donwloaded DockerToolbox-1.9.1f.exe and kicked off Docker Quickstart Terminal on Windows 10.
Did not go well.

So switched to CLI as following and always ends up with the error.

VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Write)" at line 493 of file VBoxManageModifyVM.cpp

Sounds like you're having some path issues.

1. Right click on "This PC" / "My Computer" on windows desktop
2. Select "Properties"
3. Go to "Advanced" tab
4. Click "Environment Variables..." at the bottom
5. Under System Variables click "New..."
6. Set "Variable name" to "VBOX_INSTALL_PATH"
7. Set "Variable value" to "C:\Program Files\Oracle\VirtualBox" (or where your vbox is installed)
8. Select "OK" and close all the other settings windows

Arigatou, FrenchBen

It has been set and conducted my operations under the env var set.

C:\Windows\System32>env | grep VBOX
VBOX_INSTALL_PATH=C:\Program Files\Oracle\VirtualBox
VBOX_USER_HOME=C:\Users\norio.VirtualBox

C:\Windows\System32>cd %VBOX_INSTALL_PATH%
C:\Program Files\Oracle\VirtualBox>ls
DbgPlugInDiggers.dll VBoxEFI32.fd VBoxSVC.exe
...

[FrenchBen]

Doitamashite @yugou - Is it working now? or still having the same issue?

[yugou]

The reported glitch was under VBOX_INSTALL_PATH var set.

[FrenchBen]

Good to hear it's working

[yugou]

No, it's NOT working.

[FrenchBen]

I thought from above, you said the glitch was in the VBOX_INSTALL_PATH ?
Can you try to uninstall Virtualbox and re-install it?

[yugou]

Sorry for the confusion.
Irrespective of VBOX_INSTALL_PATH is set or not, I face the
VBoxManage.exe: error: Context: "LockMachine(a->session, LockType_Write)" at line 493 of file VBoxManageModifyVM.cpp

I tried re-installation a couple of times, but no luck.

[FrenchBen]

Can you open Virtualbox and confirm that the 'default' machine has been created and that you can manually start/stop it?

What anti-virus are you running?

[yugou]

Although the error, yes, a half cooked default is created and able to start/stop.
Why I say "a half cooked" because

1. Starting it on VirtulBox Manager, but I do not get the console so cannot operate in the default OS.
2. My Windows is x64, but the default OS was created as 32bit Linux.

What anti-virus are you running?

No anti-virus running on my Windows, but only Defender.
In case, I turned off the Defender and tried the same, but resulted in the same error.

[FrenchBen]

It's very difficult for me to help when this isn't something happening on my OS and also very specific to VirtualBox - Can you provide a screenshot of the interface that exist for this VM?
Adapters + Host-Only Adapters

[yugou]

Is this enough, FrenchBen?

[FrenchBen]

Could you give me the screenshots from the Virtualbox App? I'm more familiar with those.

Thanks!

[yugou]

Ok, sure.
