It is common that emulation can be confused with CPU virtualization, that is why this article will explain what this process consists of and also explains how it can be enabled.
CPU virtualization
Feature that allows the operation of virtual machines with high efficiency
The virtualization of the CPU is based on the performance in the equipment so that the guarantee is given that it has the possibility of operating in the processor that a computer has. An example of its function can be exposed in processors such as Intel and also AMD, which have this resource to run on the computer system.
It can be defined as a function, property, or characteristic exhibited by specific hardware that allows it to be applied as a verbose processor. Through this, it is possible to operate the operating system with a more efficient, optimal and effective power; so the performance of the computer also increases.
It optimizes the processor so that in the operation of complex procedures it can be executed without any inconvenience, for this reason it is often confused with emulators which have similar functions. Emulators are responsible for running various software on a different operating system than the one the program is written on.

This gives you the possibility that the computer can support the properties of a program directed to a specific operating system. In the case of virtualization, the CPU fragments the physical processes that are going to be executed in a certain time into sections so that each virtual machine applies the corresponding operations consuming the physical resources allocated, which are generally few.
It has associated the hosts that are integrated in the machines so that the operation configuration is established in an equitable way, keeping the data transfer work determined, with this each integrated machine can be applied as if it presents a constitution of different virtual processors .
When it is based on software, it presents an application code so that the processor executes it directly, thus guaranteeing the performance of the equipment and that the consumption of resources does not exceed the limit established in the configuration. In the same way, with this code there is a wide range of benefits which are responsible for translating each task processed by the CPU.

Features
Virtualization can be assisted by specific hardware giving the advantage of applying the guest mode, which consists of an additional code that allows the processor to go from a guest state to a root one. It does not require a direct translation of the initial code so it operates with a speed very similar to the native of the system.
Another feature of CPU virtualization is that they include various updates so that you have the option of multiple exits from the guest mode, speeding up individual processor execution. For this reason, it has several models that this machine can acquire to present a higher level of performance in the various applications.
It introduces a list of overloads that are characterized by different capacities which are elaborated according to the tasks that the virtual machine has. Each workload that this equipment uses for the operation of the instructions given by the user so that it can collect the data associated with the programs.
Through its characteristics, several hardware can share the resources of the equipment, so that they can be executed at the same speed with the possibility of migrating to the associated infrastructures to carry out the corresponding workloads that are in the system configuration.
With virtualization, the development of various projects is facilitated, among these is the Arduino, to learn more about this, you are invited to read about Arduino projects
Activation
As it is an essential requirement in virtual machines for their basic operation, the corresponding activation of CPU virtualization must be carried out. With this it is possible to execute a large number of operations that are based on the translation of codes in an independent way and maintaining the performance of the equipment.
The first thing to do is to check if the virtualization of the CPU is activated in the virtual machines, for this you must identify the processor you have in the computer, then you must press the command "Windows key + S key". A box is displayed in which the specific information of the system must be entered.
You must enter "ark.intel.com" to enter the number of the corresponding processor, accessed in "Advanced Technologies" where the number and characteristics of the equipment must be rewritten, a list is displayed with the name of the specific processor available indicating whether virtualization is enabled.
To activate virtualization, it must be executed from the computer's BIOS but it is important to remember that there are many ways due to the fact that there are different motherboards on the market, which have a specific procedure for each of them, that is why in this section is going to explain the general way of activation.
The first step that must be carried out is to restart the computer, with this we proceed to enter the BIOS by pressing the Del Key, it can also be done with the F2 key. Now the advanced features are selected to display the equipment configuration options, which depending on the motherboard can be called VT-d or Vd.
A panel is displayed with options for various functions that can be configured, in this case you have to press the activate button where it says Intel-VT or AMD-V, depending on the case. Then the modifications made are saved and the computer restarted, with this we complete the CPU virtualization activations.
