Based on a first-hand survey of virtualization Technology (virtualization) in the U.S. CIO Magazine, you may have actually used virtualization technology and are satisfied with the ROI that has been brought about so far. But this today's hottest it
Competition for network virtualization technology of four major hosts in the data center
Since it is the virtualization of the host network, it is actually the virtualization of network functions on the server. Server vendors who propose such technologies hope to use this technolo
In the previous article, we mentioned the general classification of virtualization technology, which is divided into 3 categories: full virtualization, semi-virtualized, and hardware-assisted virtualization technology. And the main virtual body of our
Overview: Introduction to Virtualization Technology (KVM,QEMU), installation of virtual machines, management of virtual machines (Virt-manger,virsh, etc.).
1. Why should there be virtualization technology?
If your main operating system is windows but you need to work on Linux, like VMware (need to pay ...). Or Virtua

Libvirt is an application interface, daemon process, and management tool designed to manage platform virtualization technology more conveniently. It provides the following functions:

The networked storage system itself is still limited to the local area network, which can not meet the requirements of the data resource sharing and integration of the department, province, City and county four-level information system. At the same time, with the deepening of government
Virtualization architecture, the most popular technology in the IT field in recent years, it has evolved from a simple PC virtual machine to a complete enterprise-level virtualization architecture from server virtualization to user interface virtualization, network
interruption through DMA write requests. Because the target memory address needs to be embedded in the DMA request, this architecture needs to access all memory addresses and cannot be isolated. The interrupt-remapping architecture of VT-D uses a Message ID instead of a memory address when writing a DMA request. A table can be used to differentiate Virtual Machine regions by ID. Direct I/O device allocation and I/O device sharing replace the traditional tec
(CPU, memory, Disk input and output, etc.) and associate these types of resources to the Cgroup specified in the hierarchy to implement the resource allocation.Note: Cgroups is the underlying foundation of the Resource Management Control section for IaaS virtualization (KVM, LXC, etc.), PAAs container sandbox (docker, etc.)

Analysis of VMware Server Virtualization Technology
Server Virtualization has become one of the hot topics. At present, the leader in the server virtualization market is VMware. In addition, the strength of Microsoft and Citrix cannot be underestimated. Before selecting a server
Fully integrated network virtualization technology (1)
Server virtualization technology changes CPU, memory, disk, I/O, and other hardware into a "resource pool" that can be dynamically managed, thus improving resource utilization and making IT more adaptable to business changes. IT systems are composed of network ser

At present, enterprise Data center is becoming more and more popular, enterprise business application is more and more complex, it has posed serious challenge to the traditional resource fixed allocation mode of IT infrastructure. It has become increasingly clear that the crux of many IT systems built on traditional models is not the lack of performance but the ability to adapt to change. As the industry's first deliverable (product) fully implemented server
Server virtualization is not a new concept. More than 40 years ago, IBM launched the virtualization concept on its big machine. However, server virtualization, the "Old Wang Xie Tang Qian Yan", was not "flying into ordinary homes" until nearly two years. It has sprung up. Today, if your server is still not virtualized, and you don't even want to understand the ad
The rapid development of container technology has squeezed out many sites of traditional virtual machine technology. No way, in the boot speed and performance, the container has too many advantages, and the development of virtual machine technology is too slow.Now, fueled by
Random computer and network environment, the gradual maturation of virtualization technology, coupled with the main mainstream it media rendering, international manufacturers marketing offensive, as if the virtual wind has swept China overnight, to the urgent need to the point, from a few people's studio to have tens of thousands of PC state-owned enterprises, nowhere to talk about
Installation and use of KVM virtualization technology under LinuxThe advent of the cloud era, the widespread use of virtualization. Let's redefine the technology . And today's well-known virtualization products are VMware vsphere, HYPER-V,XEN,KVM. VMware is a marketplace for
Server virtualization technology is implemented to reduce the physical infrastructure and save space and money.
Virtualization Technology is a good way to use physical servers more efficiently and effectively. You can also integrate existing servers to save space and money for the data center. However, the methods for
