feasible method in traditional x86 is "Ring deprivileging", such as the privileges of the guest operating system kernel Level from ring 0 to ring 1 or ring 3, that is, "eliminate" the privileges of the guest core, to lower than the ring 0 in which VMM is located, so that VMM captures sensitive privileged instructions.3. SummaryThe idea of semi-virtualized is to let the customer operating system know that they are running on the virtual machine, working in a non-RING0 state, then it was original
Ubuntu is about Ubuntu 7.10 (or ?) The introduction of virtualization technology is called KVM, and KVM is the Kernel-basedVirtualMachine, which is not related to Ubuntu. This Is A virtualization technology supported by Linux Kernel, but the Linux Kernel used by Ubuntu7.04 exactly supports KVM. In Ubuntu, as we all kno
Most of the time, hardware virtualization Technology extensions should is enabled in motherboard BIOS in order to Run recent OS and applications. Specifically Windows 8 and 8.1 require VT-X/AMD-V enabled processors even to install it on virtual machine. Your PC processor and motherboard should support this feature, if they don ' t, you can ' t does anything to get this feature be Cause it ' s a built-in har

Hierarchical structure of computer systemsNow the computer system is a huge whole, the whole system is very complex, so the computer system is divided from bottom to layer, each level is like the previous level to render an abstraction, and
solution to the above fault problem. Because routers are often used as a bridge for protocol conversion, a router based approach can also provide interoperability between heterogeneous operating systems and multi-vendor storage environments.
Third, the development foreground of the virtual storage technology
① Each method has its advantages and disadvantages
Host-based and storage based methods are most attractive to early-stage users because they
a startup request number, the server received, according to different mechanisms, to send the starting data to the workstation, after the workstation download startup data, System control is transferred from Bootrom to certain areas in memory and boots the operating system.

IBM's Steve Mills first proposed the Voi (Virtual OS infrastructure) architecture idea Voi model is based on the client-side dummy
Background:
In the automated testing industry, individuals feel that the main language is Python, java. This discussion is based on the Python automation framework design and case development, using Python know its benefits, but according to the actual project needs have a lot of oncoming difficulties-host migration, environmental clutter, external impact. These problems are very bad, causing great trouble for the developers, which leads to the inability to maximize the role of automated testi
Http://www.sdnlab.com/12077.html SdnlabHow to realize the isolation of address space and data traffic between different tenants and applications is one of the first problems to realize the virtualization of data Center network. The so-called isolation of the address space means that the network (IP) addresses between different tenants and applications do not interfere with each other. In other words, two tenants can use the same network address comple
How to learn VMware virtualization TechnologyVirtualization and cloud computing, is a comprehensive technology, need to master the network, storage, server and other aspects of knowledge, have a certain hands-on practical ability.1 requires VMware workstation and network FundamentalsIf you are just a beginner, able to install the operating system for your laptop, desktop, install Office, QQ and other common
Recently, we have been studying virtualization technology, have a certain understanding of the VMware virtual machine, the latest whim, can you install a virtual machine in a VMware virtual machine?Then the problem comes, first of all, you need a computer, VMware software, (My Computer Configuration slag, memory a bit too much), so we can start, first in VMware to load an Ubuntu system, (preferably 64-bit),
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
In xen, PV is semi-virtualized, and hvm is fully virtualized. PV can only be used in Linux kernel systems and is more efficient. hvm can Virtualize all common operating systems (windows can be used ), the theoretical efficiency is slightly lower than pv. In addition, hvm requires CPU virtualization command support (the CPU must enable intel VT or AMD-V). PV does not have this requirement.KVM is an emerging virtual
Xen: Linux #8482; kernel virtualization technology overview-Linux general technology-Linux programming and kernel information. For details, refer to the following section. Xen is applicable to Linux™A virtualization technology of the kernel allows you to install and test ne
What is virtualization?
Virtualization means that computer components run on a virtual basis rather than on a real basis. Virtualization Technology can expand the hardware capacity and simplify the software reconfiguration process. The virtualization
Containerized technology (containerization).You may have a lot of doubts: what exactly is a container and how does it work? What does Docker and kubernetes mean, and what is the use of Google Container engine and managed VMS? How are they related, and how can we build a powerful service through containers and make them available in a large-scale cluster of produc

machines will also collect all traffic, these traffic must contain a lot of unencrypted sensitive data such as user name, password, etc., it is assumed that these virtual machines have a machine is hacked or illegal use, this will bring great security problems.Scenario Two: Virtual hosts for applications and databases are randomly allocated on a host in a virtualized clusterThis scenario is actually a combination of scene one and scene two, most of the customers in order to avoid a single hardw
