From Physical to Virtual: Converting Machines for Enhanced Flexibility and Efficiency 

From Physical to Virtual: Converting Machines for Enhanced Flexibility and Efficiency 

It is widely accepted that virtual infrastructure and computing are becoming the norm rather than the exception. The benefits of virtual computing significantly exceed the drawbacks, and as a consequence, real workstations are increasingly being converted to virtual machines. 

Virtualization provides several advantages to enterprises, including resource optimization, scalability, and easier management. The simplest technique to implement virtualization is to consolidate physical servers into virtual servers using physical-to-virtual (P2V) conversion. 

The process of converting and transferring a physical computer image (including its operating system, data, and applications) into a virtual machine (VM) is known as P2V. There are two techniques for P2V: hot P2V (done while the physical server is operating) and cold P2V (performed while the server OS is not running). 

This article will explore why you should convert a physical computer to a virtual machine. 

What Exactly Is the Definition of Physical to Virtual Conversion? 

P2V conversion is the process of converting a physical machine into a virtual machine. This enables you to preserve your physical machine’s state, data, apps, and system setup while benefiting from the flexibility and efficiency of a virtual environment. P2V conversion may be done using specialist software P2V tools that can construct a VM from the disk image of a physical system. 

Why Convert a P2V Machine? 

There are numerous reasons why organizations might want to convert their physical servers to virtual machines (VMs); the most notable are the following: 

Migrate to the Cloud 

Traditional on-premises IT infrastructures are unsuitable for cloud migration and reaping their full advantages. Consolidating physical servers into virtual machines (VMs) is the first step toward cloud migration. From VMs, you can migrate to private and public clouds. 

Reduce a Datacenter Footprint 

Consolidating real servers into virtual machines minimizes the total footprint of the IT infrastructure in terms of resource use and energy consumption. Furthermore, less storage and network equipment mean further cost savings for the firm. 

Simplify IT Infrastructure Administration 

A virtualized IT infrastructure is easier to administer than a physical system. To manage physical infrastructure, you must physically access the individual servers and consoles using login credentials. Virtualized servers, on the other hand, provide for a single login and access to all VMs via a centralized panel. 

P2V’s capabilities extend beyond access and maintenance. They also provide enhanced IT infrastructure management features such as server provisioning, digitization, monitoring, safety, and disaster recovery. 

Retiring Aging Hardware 

Due to increased maintenance costs, decreased performance efficiency, energy inefficiencies, and unscheduled downtime, aging hardware incurs extra expenditures for the company. Converting such hardware into a VM improves its performance and flexibility over utilizing it in its physical state while also rationalizing resource allocation and use. 

Provide Assistance with a Test and Development Environment 

One of the most important components of building a dependable IT infrastructure is providing a testing environment for developers. If you make a mistake when testing the physical environment, you may face some difficulties and lose time. P2V makes it simple to set up a virtualized test environment that captures snapshots of the working environment. 

You can make modifications, and if the application fails, you can roll back the snapshots and try again an unlimited number of times. This way, you save time and may make adjustments with confidence. 

Support Legacy Software 

Legacy apps are incompatible with contemporary hardware and operating systems. It’s also difficult to execute these programs when there are hardware breakdowns or other challenges. Virtualization is the only way to continue utilizing old software in these instances. Furthermore, it extends the usage of the product by increasing uptime. 

Preparing for a Physical to a Virtual Conversion 

When building VMs from actual computers, there are three critical actions to take: 

  1. Determine the new VM’s resource usage. It is a recipe for disaster to virtualize physical servers without first monitoring their resource utilization. Before attempting a physical-to-virtual transfer, you must assess how much processor power, RAM, and hard disk space your present physical server requires. This will tell you if the available hosts can or cannot accommodate such a server as a VM. 
  1. Prepare the source. The next step is to set up the source server if the available hosts can accommodate the physical server as a VM. Some jobs you might do include the following: 
  • Make a backup of the complete source physical server. 
  • Using remote logins, cache your current password. 
  • Make sure you know the password for the local administrator. 
  1. Clean up the source. Before doing any P2V conversion, you must send the necessary data. This shortens the time required to virtualize the physical server and decreases the possibility of transfer errors. As a result, you should remove any unnecessary items, such as memory dumps, Windows update uninstall files, and obsolete versions of files. Furthermore, following the conversion procedure, deleting any software you no longer need on the virtual server is important. 

What Use Cases Aren’t Suitable for P2V Conversions? 

P2V conversion is usually a challenging procedure. For starters, it does not erase any system setups or application issues that may be present on the real server. Second, the virtualized system may never be optimized for specific workloads. Virtualizing domain controllers (DCs), exchange servers, and systems that rely on specialized hardware are a few workloads where physical-to-virtual conversion is unacceptable. 

Exchange Servers 

Virtualizing Exchange servers, like virtualizing DCs, is dangerous. The P2V conversion has the potential to fail or damage the exchange database. The resultant virtualized server may be exceedingly sluggish in certain circumstances, significantly harming company operations. When converting Exchange servers to virtualization, it is best to deploy the VM first and then reload the exchange on that virtual machine. 

Domain Controllers 

When attempting to virtualize a DC, several possible complications may develop. A hot migration, for example, might result in a DC that is out of sync with others. Even if the cold migration is successful, turning on the old DC while the new DC is operating might result in duplicate instances. 

Systems That Rely on Legacy Hardware 

Converting servers that need specific hardware, such as licensing dongles and fax boards, might jeopardize the P2V process. This is due to the possibility that mimicking such hardware in a virtualized system would fail. Because contemporary virtualization technologies do not support 16-bit guest OSes, it is impossible to virtualize a DOS-based program operating on 16-bit hardware. 


The primary goal of P2V, and hence virtualization, is to enable enterprises to rationalize the utilization of IT resources. However, today’s company needs are continuously changing, necessitating agile IT solutions that are safe, cost-effective, and scalable to satisfy a mobile workforce’s expectations. 

Rather than searching for simple P2V virtualization solutions, you should consider a comprehensive virtual desktop infrastructure solution. There are more compelling reasons to convert a physical computer to a virtual machine, but the ones mentioned above are the primary ones.
