Computer Lab 01: Creating Virtual Machines

Virtual Machines (VMs) Summary Virtual machines (VMs) are computer files that provide functionality of a physical computer. They behave like a separate computer systems. The operating system (OS) running on the physical computer is called host and any OSs running inside VMs are called guests. VMs allow to experiment with another OS without having to install in actual physical hardware. They are safe place to test apps or websites seem suspicious as they are separated from the physical hardware. In this lab, we will learn how to create a VM in Linux, Windows, and/or MacOS.

Learning Objectives After completing this lab, students should ● be able to learn how to remove any VMs from VirtualBox, ● be able to install VMs in Linux, Windows, and MacOS, and ● be able to communicate with VMs.

Creating a Virtual Machine (VM) Removing any existing VM from VirtualBox To delete any VM from VirtualBox on Mac, Windows, or Linux, do the following steps: 1. Open VirtualBox and go to the VM VirtualBox Manager screen. 2. Select the VM and OS you want to delete. 3. To completely delete the VM from VirtualBox, choose “Delete all files” *.

* If you choose “Remove only” than the virtual machine is simply removed from the VirtualBox VM manager, but none of the actual files or associated VM, OS, VDI, or anything else is deleted. To delete the VM and associated files, choose ‘Delete all files’. 4. Delete “VirtualBox VMs” folders.

 Path: Add /scratch in front of /students/u….  Reinitialize the Mac address of all network cards

5. Click on Import button

6. Launch the xenial64 VM (Create a host adaptor by clicking File-Preferences, and then press start button)

7. Ubuntu 16.04 has started The Australian National University | 4

9. Enable Host-only Adaptor by clicking Enable and pressing OK (See Troubleshooting below if you are not able to enable Adapter 2)

10. IP address of the VM

11.

Verify that the host can communicate with the VM by using ping command
