The main purpose of a
virtual machine (VM) is to
run a virtual PC from within
a physical PC.
The host system sets up and manages the VM. The
VM can run almost any OS (depending on the
hypervisor). The VM can be sandboxed (completely
isolated) or share in the available network
resources. VMs are very versatile and are becoming
more and more common each day.

Learning.
Test a new operating
system (OS).
A new OS can be tested in a virtual
environment before making the
commitment to install it on many
systems.
Testing.
Try out a new security,
applications or patches.
VMs can be used to test applications
or patches for problems before they
are installed on a production machine.
Legacy applications.
Not all applications will
function on today’s OSs.
Some applications require legacy
operating systems to function
correctly. VMs can accommodate
this on current hardware and
operating systems.

– VM shares the physical resources of the
host machine
» Processor and RAM are the key to a good VM experience.
– Resource requirements.
» Processor: VMs can be processor intensive. A fast multi-core
processor that is capable of hardware assisted virtualization is
a must.
» RAM: each VM shares the RAM of the host; enough RAM must
be present to fulfill the needs of the host and each VM.
» Disk: VM files can grow large, especially as applications are
added; there must be enough disk space for the all the required
files.
» Security: when running a VM to test a virus, proper security
must be in place to ensure that the VM remains isolated from
the host.
» Network: the VM will share the bandwidth of the host system’s
network interface card (NIC). A high throughput NIC or multiple
NICs might be necessary.

The purpose of virtual machines is to run virtual PCs within a physical host.
They can be used for learning, testing, running legacy applications, and
increasing resource utilization.

Summary
The hypervisor is the VM manager. It is the software that manages the
resource allocations for the VMs. There are many to choose from, Windows
Virtual PC, VMWare Player, and VirtualBox are all free for non-commercial
use.
The hypervisor.
As the VM shares the physical resources of the host system, some
requirements are more important than others. A powerful processor capable
of hardware assisted virtualization and as much RAM as possible are the
important key factors.
