What is Intel Virtualization Technology (VT-X) in the CPU

Intel's hardware-assisted virtualization technology (Vanderpool Technology, referred to as VT Technology) is a simpler, more efficient and reliable approach to hardware-assisted virtualization solutions for the world's first X86 platform. It improves the ring privilege level that is assigned to the guest OS (operating system on the virtual machine) in different situations.

Achieve higher manageability in the IT environment, security and flexibility, virtualization technologies such as hardware-assisted Intel Virtualization Technology (Intel VT) are combined with software-based virtualization solutions to integrate multiple environments into a single server or computer to maximize system utilization. Abstracting software from the underlying hardware presents a new usage pattern that lowers costs, improves management efficiency, enhances security, and enables your computing infrastructure to withstand catastrophic events in the event of a disaster.

The so-called virtualization, refers to the single computer software environment divided into multiple separate partitions, each partition can be used to simulate a computer technology. The essence of its technology is to realize the management and redistribution of computing resources through the middle level, so as to maximize the utilization of resources.

The greatest benefit of virtualized partitions is that the same physical platform can run multiple homogeneous or not homogeneous operating systems at the same time, respectively, as a support platform for different businesses and applications. Partitions enable better isolation between applications, by installing different applications on different partitions, you can avoid interacting with multiple applications on the same system, including computing resource contention, the impact of a single application crash on the entire system, or the maintenance and upgrades of a single application affecting the operation of other applications. and the various applications of the system Platform environment components version of the different requirements and other contradictions, while making the system backup, migration and upgrade more simple and flexible, because of the existence of the middle tier of resource management, not only operation has become very simple, and can be easily implemented online; of course, The most important is that the partition can realize the real-time on demand dynamic allocation of computing resources, and the partition with large load can get more computing resources. When the load drops, the computing resources can be recycled, returned, or reassigned to other partitions to maximize resource consolidation and on-demand dynamic allocation.
