Mastering VirtualBox and Network Virtualization

Explore virtualization basics by reviewing VirtualBox history and versions, installing the software and guest additions, navigating the VirtualBox interface, using the extension pack, and starting or stopping virtual machines.

Trace the history of VirtualBox from Infotech to Sun Microsystems and Oracle, and review its current 5.2 open-source hypervisor for x86 PCs under the GPL v2 license, with OS updates.

Explore essential virtualization terminology, including host operating system, guest OS, virtual machine, and hypervisor, to reduce confusion. Learn how guest software like guest relations enhances performance inside the virtual machine.

Install VirtualBox on Windows by visiting the official site, navigate to the download page, download the Windows package for VirtualBox 5.2, run the executable, accept defaults during installation, and finish.

Explore the Oracle VirtualBox Extension Pack, its licensed components, and how to download it from Oracle's site, with free evaluation and commercial licensing options.

Learn how to start, pause, and save virtual machines in VirtualBox, while observing state changes such as running, saved, and paused for Ubuntu and Windows 10 VMs.

Create a virtual machine in VirtualBox by configuring memory, a dynamic VDI hard disk, and Windows 10 settings, then attach a Windows 10 ISO and run the installation wizard.

Review virtual machine settings by clicking the settings icon on the menu bar or right-clicking the VM and selecting settings, then view Windows 10 settings inside the VM.

Explore virtual machine files in VirtualBox by using show in explorer to locate Fedora workstation 26 and Windows 10 VM folders, view box and vdi files, logs, and snapshots.

Explore how to adjust a virtual machine's hardware: modify memory, processors, disk storage, and network settings in VirtualBox, including adding existing and new disks and verifying changes.

Identify unused virtual machines in VirtualBox and remove them to free disk space. Delete all files to erase the VM and its files, or XML to remove from the interface.

Learn to create, restore, and delete snapshots to capture a VM's state, revert to the saved state, and free up disk space while preserving changes like a new background.

Organize many virtual machines by creating and renaming groups, then drag and drop VMs into groups to simplify navigation in VirtualBox.

Explore virtual network card hardware in VirtualBox, configure NICs for VMs, and learn how GUI limits, CLI control, six NIC types, DHCP, and routing shape networking.

Set up a VirtualBox lab with two Fedora VMs on a common internal network, enable and configure their adapters, assign IPs, verify mutual ping, and note no internet access.

Explore VirtualBox networking modes, including not attached, nat, nat network, internal networking, host-only networking, bridge networking, and generic networking, and learn how each mode controls connectivity and isolation.

Explore how to install operating systems in VirtualBox by downloading iso images, attaching them to a vm's cd-rom, and performing Linux and Windows 10 installations for lab environments.

Install Ubuntu desktop 16.04 by downloading the image, attaching it to a virtual machine, and completing the setup with time zone, keyboard, and user account details.
