Physical To Virtual Machine
Physical To Virtual Machine:
Physical to virtual (P2V), also called hardware
virtualization, refers to the migration of physical machines to virtual
machines (VMs).
Developers using a P2V approach transfer their physical
environment into a digital one. By doing this, they use less hardware and
physical space, and reap the benefits of VMs, including more flexibility
because VMs can run on multiple platforms. P2V is commonly used for server
virtualization. It is also popular as a way for Mac users to
run Windows applications.
Data migrated in P2V includes an operating system (OS),
applications, programs and data from a computer's main hard drive. It's moved
to a VM or a disk partition.
Tools such as Micro Focus' PlateSpin> Migrate and Microsoft's vContinuum
save the data gathered from the physical machine as an image, which a hypervisor reinstalls
on a VM. The result is a VM with the same data, applications and system
configurations as the physical server being virtualized.

Benifits:
Efficiency savings. VMs require less hardware, physical
space, power consumption and repairs to run. So, migrating to them saves
operating expenses.
Flexibility. VMs can run on multiple platforms,
expanding migration options. Old hardware can be phased out and space can be
saved because multiple VMs can run on a single server.
Availability. If the hardware a VM runs on fails, the
VM can be placed on a working server with minimal downtime.
VMs are not tied to any one physical component, and therefore can be migrated
as necessary.
Testing. Developers can use VMs as a sandbox to
test new and potentially hazardous component changes or code before putting
them in a live environment.
Lifespan. Physical enterprise hardware will
eventually wear out. Virtual machines are abstracted from underlying hardware
and can last much longer. As hosts age, become obsolete or die, the VM can be
migrated to a new one.
