What is Virtualization
Virtualization is abstracted from hardware so that multiple workloads can share a common set of resources. With shared virtualized hardware, you can host different workloads at the same time while maintaining complete isolation from each other, freely switching between infrastructures and scaling as needed.
Significantly improve capital and operational efficiency through virtualization, because it can bring better server utilization and integration, dynamic resource allocation and management, workload isolation, security, and automation.
Virtualization supports on-demand self-service and software-defined resource orchestration that can be expanded everywhere. -Indoor or off-site hybrid cloud based on specific business needs.
Intel® Virtualization Technology (Intel® VT) is an ever-growing combination of technologies and features that makes virtualization feasible by eliminating performance overhead and improving security.
Technology (Intel® VT) provides hardware-assisted virtualization software while reducing size, cost, and complexity, with a focus on reducing virtualization overhead related to cache, I/O, and memory.
Solution developers and users have acquired Intel® Virtualization Technology (Intel® VT), which now serves a wide range of customers in consumer, enterprise, cloud, communications, technology, and other fields.
What is Intel Virtualization Technology?
Intel Virtualization Technology (Intel VT or IVT) is a feature provided by Intel processors that enables multiple operating systems and environments to be combined and hosted on a single processor.
Intel Virtualization Technology is the ability of processor hardware to isolate and isolate computing power. For multiple hosts. The virtual machine and its operating system.
Intel's virtualization technology was formerly known as Vanderpool. Intel Virtualization Technology is a hardware virtualization technology that can be used in conjunction with software and operating system virtualization to create a series of typical virtual computer scientist environments.
Developers, service providers, and end-users usually divide their capabilities into logical processors and assign each processor to multiple virtual machines or operating systems to separate different information systems and use their hardware processors.
Full and huge computing power. NTS environment with a preferred working configuration. Virtualization technologies such as Intel Hardware-Assisted Virtualization Technology (Intel VT), when combined with appropriate virtualization software, can maximize the use of system resources by consolidating multiple environments on a single server or computer.
It accomplishes this by eliminating any software dependencies on the underlying hardware, thereby helping to reduce costs, improve management efficiency, improve security, and make IT infrastructure more resilient in the event of a disaster.
Intel VT requires a computer with a processor, chipset, BIOS, supporting software and/or operating system, device drivers, and applications designed to use VT functions.
Therefore, the performance of the VT function will depend on your computer configuration.
Intel VT-enabled processors improve virtualization efficiency by eliminating the overhead associated with software conversion between guest operating systems and hardware platforms. In the traditional software virtualization paradigm, the host operating system and VMM ring 0 occupy the highest level of authorization.
Although guest operating systems are usually designed to run at this privilege level, they cannot be shared with the host operating system, so the guest operating system must run at this privilege level. The least privilege in ring 1.
Because the guest operating system in the pure software virtualization model runs at a lower privilege level than its designed privilege level, the VMM must perform processor-intensive software conversion when accessing host resources.
It consumes processing resources and limits the performance and scalability of the overall solution. Alternatively, any guest operating system can be modified to run on Ring 1, but this conversion may need to be done on a VMM-specific basis, and such changes may not be possible for proprietary closed-source operating systems.
Intel VT specifically grants VMM a privilege level called
VMX Root, making Ring 0 available to the guest operating system.
The additional privilege level also eliminates the need to modify the guest operating system used in the virtualized environment, and the VMM itself can be smaller and simpler, further improving the performance of the virtualized system.
What are the Features Of Intel virtualization technology?
With the help of CPU virtualization, you can completely abstract all the functions of Intel® CPU into a virtual machine (VM). All VM software can run as if it were originally run on a dedicated CPU without loss of performance or compatibility. Can be used from one Intel® processor to another, as well as nested virtualization.
You can use storage virtualization features to isolate the storage abstraction and monitoring of each virtual machine (VM). These functions can also realize real-time migration of virtual machines, improve flexibility and improve security. Examples of features include direct memory access reallocation (DMA) and extended page tables (EPT), including their extensions: dirty and accessible bits, and fast EPT context switching.
I/O virtualization features can easily port multi-core packet processing to network adapters, and directly map virtual machines to virtual functions, including disk I/O. Examples of this are Intel’s Directed I/O (VT-d), Virtual Machine Device Queue (VMDQ), Single Root I/O Virtualization (SR-IOV, PCI-SIG standard), and Intel® Data Direct Connect I ® Virtualization Technology/O Technology Improvement (Intel® DDIO).
Intel® Graphics Virtualization Technology (Intel® GVT) allows virtual machines to fully and/or share the allocation of graphics processing units (GPU) and video transcoding accelerators, which are built into Intel system-on-chip products. Examples include remote workstation connections, desktop as a service, streaming media, and online games.
Virtualization of Security and Network capabilities permits the transformation of conventional community and safety workloads into computing. Virtual capabilities may be deployed on popular excessive extent servers everywhere withinside the information center, community nodes, or cloud, and neatly co-placed with commercial enterprise workloads. Examples of technology making it appear to consist of Intel® QuickAssist Technology (Intel® QAT) and the Data Plane Development Kit (DPDK)
Does My Processor Support Intel® Virtualization Technology?
Intel® Virtualization Technology abstracts the hardware by allowing several workloads at a time to share a common set of resources. Shared virtualized hardware can carry different workloads while being completely isolated from each other, moving freely between infrastructures and expanding as needed.
