# 6.1.4 Using Pre-Built Virtual Machine Images

When using this option, you can use a ready-made DGT node image that is available for download onto your computer. You can immediately use the node on your equipment. The following images are available for download:

Basic steps to get started:

* Get ready: you must have at least 20 GB of free space available on your hard drive. You must install a program to support virtual machines (choose depending on the image used: [VirtualBox](https://www.virtualbox.org/wiki/Downloads), [VMware Workstation Player](https://www.vmware.com/products/workstation-player.html)/[Workstation Pro](https://www.vmware.com/products/workstation-pro/workstation-pro-evaluation.html)).
* You should be able to unarchive a .rar archive ([WinRar](https://www.win-rar.com/) is recommended).
* You should have a basic understanding of the Linux system and its commands. Recommended: «[Getting Started with Ubuntu 16.04](http://files.ubuntu-manual.org/manuals/getting-started-with-ubuntu/16.04/en_US/screen/Getting%20Started%20with%20Ubuntu%2016.04.pdf)» (This manual also covers the basic commands of the Linux system).
* Download the selected virtual machine image. Be sure that this is an authentic image – verify the checksum and compare it with the value in the table above. To get the checksum:

o   For the Windows operating system: open the command line interface (Press *Windows R*, type `cmd` and press `Enter`), use the *cd* command to navigate to the folder where the file was downloaded and type the command `certutil -hashfile <file> MD5`, where <*file*> is replaced by the name of the archive loaded. The screen should display the checksum, which is what you need to compare to the value in the table above.

o   For the Linux operating system: use the cd command to navigate to the download folder, type `md5sum <file>` to obtain the checksum, and compare the value to the data in the table.

* Expand the archive into a separate folder by using the archiver. Inside it, you will find virtual machine files – the configuration file and the virtual hard disk file. Open the file and edit the network interfaces by using a virtual machine manager (VirtualBox or VMWare). For more details, see [*VirtualBox.Virtual Networking*](https://www.virtualbox.org/manual/ch06.html) and [*VMWare Virtual Networking Concepts*](https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/virtual_networking_concepts.pdf).
* Launch the virtual machine and log in using your username and password (see the table above).
* Use the steps described below to control the startup of the node and conduct the necessary testing.
