Docker Toolbox is for older Mac and Windows systems that do not meet the requirements of Docker for Mac and Docker for Windows. We recommend updating to the newer applications, if possible. We recommend updating to the newer applications, if possible. I’ve been working around the issue by running the Docker for Mac host. This does present some additional challenges though when wanting to “talk” to the container from Visual Studio running on Windows under Parallels. Install Docker on Mac OS X 10.11.x. Since Docker is becoming more and more industry standard, I’m writing this post to install Docker on Mac OS X without using the installation package Docker.

Or a Linux-based container on a Mac OS X kernel. This fork is officially deprecated in favor of Parallels Driver for Docker Machine, which is compatible with Docker Machine 0.5.0+. The code and documentation here only exist as a reference for users who have not yet switched over and want to use Docker Machine v0.4.0 with Parallels Desktop for Mac.
I own a mac and I need to test a Windows Server 2016 environment with Docker on it. So I run Windows Server on a virtual machine.
I can successfully install Docker ToolBox on the virtual machine, but when I run the Docker Quickstart Terminal it says:
From what I have read here and there this could be related to nested virtualisation not being enabled, but I'm not sure. And if this is the cause how do I enable it ?
I've tried both with VirtualBox and Parallels Desktop, but I have the same error for both. Also the production system will probably run on some other (cloud) virtualisation technology, so I need to really understand the requirements.

You need to enable the features on the in the VM settings in your virtualization software. For Parallels, it looks like this would cover it.

If you have an Intel core-i* Mac, it is extremely likely that VT is already enabled in the BIOS.
But you must ALSO enable VT support in the Windows virtual machine because the Docker Engine uses Windows Hyper-V (to run a very lightweight VM to run the containers).
For Parallels @Cory Knutson has given a pointer.
I use VMware Fusion 8 on a Core i7 mid-2012 MacBook Pro.
The virtual machine settings for each VM include Processors & Memory -> Advanced which has a check box [ ] Enable hypervisor applications in this virtual machine.
This is not selected by default!
Oracle Virtual Box has a similar setting for each VM.
You will have to check with your cloud provider if VT can be enabled in their VMs.

I tried to run Docker on a virtual machine.
And error occurs:
Is it possible?

You're using Docker Machine in your Windows VM, which is actually going to create a Linux VM inside the Windows VM on your Mac. You can do that, but you need to enable nested virtualization - which I'm not sure you can do in Parallels 7.
Instead you can run Docker Machine on the Mac directly and use Parallels to create the Linux VM - which means Docker is running in a Linux VM on your Mac, and you don't need nested virtualization.
Or preferably use Docker for Mac if your OS supports it, it's the latest product and has much better host integration than Docker Machine.

Install Docker For Mac
If the VM is a Linux, you can do this without any problem - on Linux, the Docker is essentially a well-worked chroot. Thus, the Linux docker is not virtualization.
In the case of Windows, it is not so easy. Windows Docker internally uses Hyper-V to emulate the containers. Which means that you can only run, if you can use nested virtualization:
- On your host machine runs a Windows VM
- Inside your Windows VM, runs a HyperV
- HyperV is managed by the docker installed on your virtual Windows.
I tried qemu/kvm, virtualbox and vmware player. I configured them deeply and strongly, I've hacked them, I did every possible to do. Only the last worked (VMWare).
There are significant speed costs, but it may be useful for development on Linux, and then trial-test on Windows configurations.
You will need a lot of ram. At least 16G. 32G is better. A relative useful configuration would be:
- 32GB physical RAM for the physical host
- 12GB virtual RAM for the Windows VM running on it
- 8GB virtual RAM inside the Windows VM for the HyperV Linux host.
Sometimes it will be a little bit buggy, but only your HyperV will crash out, your virtual Win, or your host machine won't. It is okay for testing a docker container on a Windows machine, what you've developed on a Linux. Don't create mission critical servers on this way. :-)
