Study Notes
Virtualization and Virtual Machines
- Virtualization is a software method that allows multiple virtual computing resources to run on a single hardware platform using hypervisors.
- A Virtual Machine (VM) is a software virtualization of a computer hardware that executes programs like a physical computer and can be interacted with like a physical computer.
Characteristics of Virtual Machines
- A VM allows running multiple operating systems on a single computer.
- A VM is a discrete set of files, including:
- Configuration file
- Virtual disk file
- NVRAM settings file
- Log file
Purpose of Virtual Machines
- The purpose of a VM is to enhance resource sharing among many users and improve computer performance in terms of resource utilization and application flexibility.
- Hardware resources (CPU, memory, I/O devices, etc.) or software resources (operating system and software libraries) can be virtualized in various functional layers.
