As the official documentation says, you need to enable hardware virtualization (VT-x). to do it follow this site: http://www.howtogeek.com/213795/how-to-enable-intel-vt-x-in-your-computers-bios-or-uefi-firmware/
If this doesn’t help, then google it with your laptop model number or with you PC configuration. You must have to enable hardware virtualization (VT-x). And If you are using Hyper-V on a UEFI system you additionally need to disable Hyper-V in order to access VT-x.

In software engineering, a software design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations.

Most patterns address issues of change in software
Note: The table row definitions are in these order.
Creational patterns are ones that create objects for you, rather than having you instantiate objects directly. This gives your program more flexibility in deciding which objects need to be created for a given case.

and @reboot, which runs the command once at startup.
Note: Not all cron daemons can parse this syntax (particularly older versions), so double-check it works before you rely on it.
