VirtualBox Lab: Create, Power Off and Delete VMs

These flashcards cover key concepts from the lab on creating, powering off, and deleting VMs in VirtualBox.

What is a Type 2 hypervisor?

A Type 2 hypervisor, like VirtualBox, allows for the creation of guest operating systems that run on top of a computer’s actual (host) operating system.

What file types can be used to create virtual machines (VMs) in VirtualBox?

VMs can be created from Live Image files (.ISO), Virtual Machine Image files (.VDI, .VMDK, .VHD), and virtual appliance files (.OVA).

What are the general steps to complete the VirtualBox assignment?

1. Obtain the source file. 2. Decompress if necessary. 3. Install the VM as required. 4. Install OS-specific Guest Additions. 5. Enter the credentials in the VM’s description box. 6. Enjoy the new VM.

What should be configured in BIOS/UEFI for virtualization support?

Virtualization must be enabled in the BIOS/UEFI of the computer.

How does one secure a VM installation using an .ISO source file?

Installing from a .ISO is considered more secure because it performs a fresh installation of the operating system instead of configuring a VM that may contain malicious files.

What should be done before launching VirtualBox?

Create a folder on the Desktop named 'VirtualBox' and place all downloaded source files in this folder.

What does selecting 'Skip Unattended Installation' do?

It disables unattended OS installation and requires user interaction to complete the installation.

In VirtualBox, what is the 'Expert Mode'?

Expert Mode allows the user to see all of the configuration screens from one screen, as opposed to Guided Mode which shows them one at a time.

What factors should be considered when setting Base Memory for a VM?

The amount of memory allocated should not exceed the physical memory available on the host, and Windows VMs may require more memory than Linux VMs.

What is the purpose of 'Guest Additions' in VirtualBox?

Guest Additions are software packages that improve guest OS performance and add extra features such as support for shared folders and video.

How can one save guest OS credentials in VirtualBox?

By entering them in the VM’s 'Description' box in the settings.

How is connectivity confirmed on the Linux OS within a VM?

By using the ping command, for example, 'ping www.yahoo.com -c4', to check for network connectivity.
