What is Virtualbox
VirtualBox is a free and open-source virtualization software developed and maintained by Oracle for creating and managing multiple virtual machines on a single computer. It allows users to run multiple operating systems such as Windows, Linux, macOS, etc. on a single physical computer. VirtualBox provides a virtualization environment that enables users to install and run different operating systems in virtual machines and quickly switch between them. VirtualBox provides a range of features, including virtual machine snapshots, network configuration and sharing, virtual hard disk management, clipboard sharing, and more. Users can adjust the hardware resource allocation of the virtual machine according to their own needs, such as memory, number of processor cores, network adapters, etc. The operation and control of the virtual machine can be operated through the Graphical User Interface (GUI) of VirtualBox, and can also be managed through the command line interface. Through VirtualBox, users can perform a variety of purposes, including software development and testing, operating system learning and experimentation, application compatibility testing, and more. It can also be used to create isolated test environments, quickly deploy virtual machines, access virtual machines remotely, and more. Overall, VirtualBox is a powerful and easy-to-use virtualization software that can help users easily create and manage multiple virtual machines, and seamlessly switch and interact between different operating systems.
VirtualBox is completely free virtualization software. Oracle releases VirtualBox as open source software under the terms of the GNU General Public License (GPL) version 2, which means that anyone can download, use, and modify the source code of VirtualBox for free. You can grab the free version from the official VirtualBox website and use it in a personal or business environment. While VirtualBox offers a paid version with some advanced features, the free version is already very powerful and full-featured, suitable for the needs of most users.

There is nothing to pay attention to in the back, just keep clicking next until the installation is complete, and then open virtualbox
Modify the default location of the virtual machine, if not modified, it will be placed under the C drive by default.
Create a new virtual machine, configure the name and image.
Then follow the normal process to install a centos7 system and it will be ok
Hotkey settings:
Virtualbox is very simple to use, but there will be a problem of mouse preemption, that is, after the mouse clicks into the virtual machine, it will be preempted by the virtual machine. Unless the virtual machine is closed, the mouse cannot exit, so there is a hotkey function , after using the shortcut key, it will automatically exit the virtual machine. What I set here is F1 to automatically exit.
snapshot settings
Virtualbox also provides a snapshot function, which can quickly back up the current state of the system, and return to the state before the system backup when needed.
