The Docker-machine requires VT-x/AMD-v to build up boot2docker virtual
machine. The VMX flag should be enabled when deploying the VM into
Virtualbox. In the CI framework, it relies on Coin to expose the VMX
flag to the CPU feature. To well handle the case that the VMX could be
removed due to some CI updates, the provisioning script will assert the
process with the related debug message if VMX is not found.
