Let’s talk about AMD-V(Virtualization)!

AMD-V: Virtualization helps in creating a virtual environment on a computer system that includes the creation of virtual storage devices, hardware platforms, and network resources. The concept allows an IT organization and professionals to utilize a single server in running numerous applications.

For instance, you can create a new virtual machine with a new operating system such as Windows OS, Mac OS, Linux, and Solaris. You can then place the needed applications within the virtual machines that run in the background. Virtualization helps in minimizing the use of multiple servers, which in turn reduces the operating cost of the company.

What does AMD-V does?

AMD-V (Virtualization) from Advanced Micro Dynamics helps an organization or a professional to create a virtual environment by using the hardware resources of the host computer. With the help of the virtualization environment provided by AMD, it is possible to create a virtual machine on the host computer that runs on any operating system. Depending on the requirement, the user can allow a guest or a new user to operate the virtual machine. You can assign new privacy controls, install specific applications and improve the efficiency. For instance, if the host computer is running on Mac operating system, you can create a virtual environment that operates on Windows OS to test software developed for Windows. Such an application helps in reducing the use of multiple servers. Additionally, setting up the virtual machine on a single server improves efficiency and reduces cost.

Types of Virtualisation

The following paragraphs cover the different levels of virtualizations:

Hardware virtualization

Also known as platform virtualization, hardware virtualization functions like a real computer. Upon implementing the virtualization environment, you will be executing applications in the background. It means that you can install Microsoft Windows on a computer running on Macintosh and run apps in the background, with the help apps like iMessages or GarageBand can work. With the help of hypervisor, which is the Virtual machine manager, you will be allocating the necessary resources of the host to the virtual machine.

The host machine is the actual machine in hardware virtualization while the virtual machine acts as the guest machine. The host and the guest here represent or distinguish the operating system that runs the physical machine and the virtual machine. The hardware virtualization includes full virtualization and para-virtualization. Under full virtualization, you can simulate the actual hardware of the host on the virtual machine. In para-virtualization format, the guest applications run isolated. However, it is necessary to modify the programs to run in the guest environment.

Desktop virtualization

Unlike the hardware virtualization, the desktop virtualization is a concept that separates the physical machine with that of the logical desktop. Virtual desktop infrastructure is an advanced format of the hardware virtualization. In this environment, you will be interacting with the virtual machine using a different desktop computer or a handheld device using network connection such as the Internet, Wireless LAN, and LAN. In this arrangement, the physical computer acts as the server computer that is capable of hosting virtual machines for multiple users.

Desktop virtualization is helpful for organizations that are continuing to virtualize the data collection center, as it helps them to take the benefit of continually, predictability and quality of service provided by the virtual desktop infrastructure.

For example, IBM and HP are offering a hybrid virtual desktop infrastructure that helps in improving the distributed client computing. Using this technology, a client will possess the ability to move specific environments of the workload from their PCs and selected devices to the data center servers, which helps in creating an organized virtual client environment. Such a setup is helpful for the user because they can access the content from any location without the physical computer.

As users are moving between work locations, they can access the same content present on the physical computer from anywhere using any device. IT administrators benefit from such an environment, as it is efficient to control the client environment and respond quickly according to the requirement of the business and user.

Session virtualization

Session virtualization is part of the desktop virtualization environment, where multiple users gain access to connect to a single computer using a network connection. Every individual connecting to the computer has access to a desktop and personal folder. Using multiseat configuration is beneficial in session virtualization because it helps multiple users to connect to a single PC using the numerous monitors, mice, and keyboards.

Nested virtualization

Nested-Virtualization

Nested virtualization is an environment where the user will be running one or more hypervisors within a single hypervisor. It means that you will be capable of running a virtual machine within a virtual machine. Such form of virtualization is helpful when operating systems improve built-in hypervisor functionality. For example, it is possible for the Windows 7 operating system to run applications developed for Windows XP using the built-in virtual machine feature.

Creating a nested virtualization environment is only possible when the supported host is capable of providing the necessary hardware virtualization capability. However, if a particular architecture is unable to provide the support for the hardware-assisted virtualization, then it is possible to enable it using specific software techniques. For instance, Intel included VMCS shadowing technology since the development of Haswell microarchitecture. The shadowing technology offers the needed hardware support and accelerates the performance of nested virtualization. Nested virtualization is beneficial when compared to the existing Infrastructure as a Service (IaaS) technology.

Final views on AMD-V?

Virtualization is an environment where you will be creating a virtual environment on a physical machine that runs on a different operating system. It means you can operate Mac and supported applications on your physical computer that runs on Windows OS. The benefit of virtualization is that it reduces the operating cost and increases efficiency. As organizations are moving towards reducing cost and increasing productivity, virtualization holds a promising future. Developers, designers, and testing engineers profit from the use of the virtualization concept, as they can create multiple virtual machines on their physical computer running on different operating systems and applications in the background.
