Libguestfs

Have you ever thought about opening a toy box and taking out different toys from it to play with? Well, imagine you have a toy box full of different operating systems like Windows, Linux, and macOS. But, instead of a toy box, you have something called a hypervisor which is like a magical box that can run multiple operating systems at the same time.

Now, let's say you want to check what's inside a toy car without taking it apart. You can use a toy toolset to open it and see what's inside. Similarly, libguestfs is a toolset that allows you to access and modify files and settings in different operating systems running on the hypervisor. It acts like a toy toolkit that allows you to tinker with different parts of the operating system without breaking anything.

For example, you can use libguestfs to access and modify files on a virtual machine, such as changing a setting in Windows or updating an application in Linux. It is useful for developers, system administrators, and other technical people who need to work with different operating systems at the same time.

Think of libguestfs as a toy toolkit for accessing and modifying different operating systems running on the hypervisor, making it easier for people to work with multiple operating systems on the same machine.
