What is Virtual Box? - How to Use Virtual Box ?


What is Virtual Box ?


Oracle virtualbox is a software which allow users to run multiple operating system in a single machine and to freely switch between OS instances running simultaneously. It can create and manage guest virtual machine each with a guest operating system and its own virtual environment.

What is Virtual Box? - How to Use Virtual Box ?
VirtualBox is open-source software for virtualizing the x86 computing architecture. It acts as a hypervisor, creating a VM (virtual machine) in which the user can run another OS (operating system).

The operating system in which VirtualBox runs is called the "host" OS. The operating system running in the VM is called the "guest" OS. VirtualBox supports Windows, Linux, or macOS as its host OS.
When configuring a virtual machine, the user can specify how many CPU cores, and how much RAM and disk space should be devoted to the VM. When the VM is running, it can be "paused." System execution is frozen at that moment in time, and the user can resume using it later.

How to use Virtual Box?


When using a traditional you need to install the operating system on a physical machine for evaluating software that cannot be installed on your current operating system.
Oracle VirtualBox is what you need in this case, instead of reinstalling software on your physical machine. VirtualBox is designed to run virtual machines on your physical machine without reinstalling your OS that is running on a physical machine. One more VirtualBox advantage is that this product can be installed for free. A virtual machine (VM) works much like a physical one. An OS and applications installed inside a VM “think” that they are running on a regular physical machine since emulated hardware is used for running VMs on VirtualBox. Virtual machines are isolated from each other and from the host operating system. Thus, you can perform your tests in isolated virtual machines without any concerns of damaging your host operating system or other virtual machines. Today’s blog post explores how to use VirtualBox and contains the following sections:



- How to set up VirtualBox?

  • Enabling CPU virtualization feature
  • Downloading the VirtualBox installer
  • Running the installer and defining the installation options

- Deploying a new VM

  • Creating a virtual machine
  • Installing a guest OS

- Shared folders and clipboard
- Making a VM copy
- Using snapshots
- How to use VirtualBox for recording video inside the VM



Operating Systems Supported by VirtualBox

VirtualBox supports a long list of host and guest operating systems. A host OS is the operating system installed on a physical machine, on which VirtualBox is installed. A guest OS is an operating system installed on a virtual machine running inside VirtualBox. VirtualBox can be installed on Windows, Linux, macOS, Solaris, and FreeBSD. On VirtualBox you can run VMs with Windows, Linux, macOS, Solaris, FreeBSD, Novell Netware, and other operating systems.

What is STP? - Explain Advantages and Disadvantages

The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. STP is a protocol. It actively monitors all links of the network. To finds a redundant link, it uses an algorithm, known as the STA (spanning-tree algorithm). The STA algorithm first creates a topology database then it finds and disables the redundant links. Once redundant links are disabled, only the STP-chosen links remain active. If a new link is added or an existing link is removed, the STP re-runs the STA algorithm and re-adjusts all links to reflect the change. STP (Spanning Tree Protocol) automatically removes layer 2 switching loops by shutting down the redundant links. A redundant link is an additional link between two switches. A redundant link is usually created for backup purposes. Just like every coin has two sides, a redundant link, along with...
