Docker Toolbox: Doesn't have VT-X/AMD-v even if it is enabled

Tried running Docker Toolbox on my Windows 10 Home 64-bit machine.

also, Hyper-V is already enabled!

But when running the Docker Quickstart Terminal, it always shows "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"!

In your second screenshot you are showing the Windows feature called Windows Hypervisor Platform. This is not the same as Hyper-V. Scroll up and you'll see a checkbox for Hyper-V. – n8te – 2019-05-31T06:55:49.097

You might have to disable Core Isolation in Windows Defender as well as it may "steal" VT-x/AMD-v: https://superuser.com/a/1366359/19943

Please indicate which version you have installed, use winver, to determine that information. Your question cannot be answered without this information – Ramhound – 2019-05-31T11:55:57.090

I have Windows 10 Home 64bit Version 1809 – reiniellematt – 2019-05-31T23:27:42.343

Since you have Windows 10 Home Hyper-V cannot be enabled. You should edit your question to reflect that fact. It currently indicates you have enabled it. Is Docker Quickstart Termina part of Docker Toolbox or Docker for Windows? Edit your question instead of submitting a comment – Ramhound – 2019-05-31T23:45:56.140

Long story short:

Replace string create -d virtualbox with create -d virtualbox --virtualbox-no-vtx-check

in C:\Program Files\Docker Toolbox\start.sh

~~Context TLDR~~

Home Edition does not support Hyper-V I was able to use VirtualBox at Home but not docker inside virtualbox with the same message, yet, even when I upgraded to Windows Pro, I had the very same issue as you in spite of having UEFI (Bios) SVM = AMD-x version of VTX, I had disabled Hyper-V as it is possible only at Windows Pro version, but what seems to help me is running docker toolbox manually via command like this with a parameter --virtualbox-no-vtx-check docker-machine create -d virtualbox --virtualbox-no-vtx-check which apparently suppresses that check "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

I had the same problem. SVM ect. was enabled in my BIOS but the error was still shown. The answer by FantomX1 helped me to get going. Try this:

Open C:\Program Files\Docker Toolbox\start.sh with an Editor
Replace line 69 from

"${DOCKER_MACHINE}" create -d virtualbox $PROXY_ENV "${VM}"

"${DOCKER_MACHINE}" create -d virtualbox --virtualbox-no-vtx-check $PROXY_ENV "${VM}"

Open Docker Quickstart Terminal.
Done :)

1It's line 69 in Docker Toolbox 19.03.1 (Jul 31, 2019). – Karsten Silz – 2020-01-13T09:38:25.903

thanks Karsten. I replaced the line number in my answer. – SergejoWizz – 2020-01-15T19:59:47.803

yep, thanks, I realize I somehow forgot to add it as I planned in a hurry :) – FantomX1 – 2020-02-07T17:48:13.677

But when running the Docker Quickstart Terminal, it always shows "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"!

You can try the following solution.

Within an elevated PowerShell environment run the following command:

1) PS > bcdedit /set hypervisorlaunchtype off

2) You should verify Core Isolation is disabled.

Source: This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory

Additionally, you should disable any hardware virtualization features, of any security products you might have installed.

Hyper-V is already enabled!

You absolutely DO NOT have Hyper-V installed on a Windows 10 Home installation.
