boot2docker fails to start on windows 7

Question

I recently installed boot2docker on my windows 7 64bit machine with all dependencies (VirtualBox etc). However, when I executed it, it failed to start the docker server and preconfigured shell. From the cmd I could read the following exception:

Failed to start machine "boot2docker-vm"

Answer 1

It turned out that the problem was the disabled virtualization. I found this by running VirtualBox and trying to manually boot the "boot2docker-vm" vitual machine. You can usually enable virtualization from the BIOS under CPU or Security settings. If you are not sure if your mache supports virtualization you can check it by using something like speccy.
