About Virtual Machines
A virtual machine is a software computer that, like a
physical computer, runs an operating system and
applications.
• Operating system
• VMware Tools™
• Virtual resources like:
– CPU and memory
– Network adapters
– Disk controllers
– Parallel and serial ports

Benefits of Using Virtual Machines
Physical Machines:
Difficult to relocate
• Moves require downtime
• Specific to physical hardware
Difficult to manage
• Requires physical maintenance
• Hardware failures cause downtime
Hardware has limitations
• Hardware changes limit application support.
• One-to-one relationship between application and
server.
Virtual Machines:
Easy to relocate
• Encapsulated into files
• Independent of physical hardware
Easy to manage
• Isolated from other virtual machines
• Insulated from hardware changes
Provides the ability to support legacy
applications
