Why Virtual Machine

• Why is it necessary to run two, three or more
  operating systems on one computer?

flexibility
9
Benefits

• Ease of use
• Users may switch between operating systems and
  applications with the click of a mouse without
  Repetitive rebooting and relaunching.
• Affordability
• one computer becomes capable of running multiple
  operating systems, applications and services.
• Security
• Operating systems and applications running within
  a virtual machine may be "cut off " from other
  environments.

10
Benefits

• Safety
• Changes to virtual machines do not affect the
  day-to-day Windows environment and changes that
  might be catastrophic within a virtual
  environment may be discarded when no longer
  needed.
• Legacy support
• Users may upgrade to new hardware and operating
  systems, yet virtual machines maintain the
  ability to run older software that would
  otherwise crash in the new environment.
• Standardization
• avoids bugs caused by minor differences between
  PC hardware systems.
• Configurability
• This allows users to create a wide variety of
  testing environments.

11
Benefits

• Guest operating system flexibility
• Virtual PC supports a wide variety of x86
  operating systems.
• Easy Installation
• Convenience
• All virtual machines, whether running, suspended
  or saved, are managed through a single convenient
  user interface.
• Host Integration.
• Integrating applications makes interoperability
  between the guest and host operating systems a
  snap.

12
Applications

• Technical Support
• Enable an entire department to be backwards
  compatible even while upgrading to new hardware
  and operating systems that would normally cause
  your legacy applications to crash.
• Set up any number of user-specific system
  configurations, on a single computer for
  real-time scenario testing and evaluation.
