You must have a CPU with the VT-x features enabled, which is typically done via the BIOS. Also, you need at least 8GB of ram to run the sandbox properly.

@Michael Young... It says "Failed to enable and lock VT-x features".... but you have mentioned "You must have a CPU with the VT-x features enabled".... error ,sg says "failed to enable".... can you pls clarify what is required here ? I am also getitng below error :

Failed to open a session for the virtual machine Hortonworks Docker Sandbox.

VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED).

VT-x is a hardware feature in most modern CPUs. It is can be enabled/disabled in the BIOS of your computer. If you do not have the feature, then Virtualization won't work (VMWare or VirtualBox). You can read more here at this link: http://www.howtogeek.com/213795/how-to-enable-intel-vt-x-in-your-computers-bios-or-uefi-firmware/.

I can't give you specific instructions on how to enable this feature, as it is different for every make and model of computer. You can also read more here: http://www.itworld.com/article/2981515/virtualization/virtualbox-diagnose-and-fix-vt-xamd-v-hardware...
