Virtuaalmasinatel, also known as virtual machines (VMs), are software-based emulations of computer systems. They allow a user to run multiple operating systems and applications on a single physical machine. Each virtual machine operates independently of the others and the host system, creating isolated environments. This isolation is crucial for various purposes, including software development, testing, security research, and running legacy applications.

The core technology behind virtual machines is called a hypervisor, also known as a virtual machine monitor (VMM). The hypervisor is a layer of software or firmware that sits between the physical hardware and the virtual machines, managing and allocating resources like CPU, memory, and storage to each VM. There are two main types of hypervisors: Type 1 (bare-metal) and Type 2 (hosted). Type 1 hypervisors run directly on the host's hardware, while Type 2 hypervisors run as applications on top of an existing operating system.

Virtual machines offer significant advantages. They promote resource utilization by consolidating multiple workloads onto fewer physical servers. They also enhance flexibility, allowing for quick deployment, migration, and replication of entire computing environments. Furthermore, VMs provide a safe sandbox for testing potentially risky software or configurations without impacting the underlying host system. This makes them indispensable tools in modern IT infrastructure and cloud computing.
