Virtual machines are commonly used for a variety of purposes, including software development and testing, server consolidation, and running legacy applications on modern hardware. They provide isolation between different operating systems and applications, making it easier to manage and maintain multiple environments on a single physical machine.
Virtual machines are created using virtualization software, which simulates the hardware components of a physical computer, such as the CPU, memory, storage, and network interfaces. Users can install and run an operating system on a virtual machine just like they would on a physical machine, allowing them to use the full capabilities of the operating system within the virtual environment.
Overall, virtual machines offer a flexible and efficient way to utilize hardware resources and run multiple operating systems and applications on a single physical machine. They are widely used in both enterprise and consumer environments for a variety of purposes.
