not meet the application of rapid expansion of flexibility, can not meet the application of higher levels, such as the demand for Paas\\\\saas, or the need to pass the standard framework of control, mass operation. This is when the contradiction is prominent, is also the cloud day. Therefore, in the case of financial and human support, the infrastructure can use existing virtualization to further the cloud computing environment (also consider network, storage, process input), is possible, but n

The current traditional network may not support the scalability required for large-scale server virtualization and automated configuration in the infrastructure-as-a-service model, but the new network virtual method may even be a network manager hypervisor ), it will change everything. Currently, more than 50% of servers are used as virtual machines. Each virtual machine is connected to the virtual network through a vswitch and network adapter. These

resources will work in symmetric mode and be deployed synchronously, rather than one other. The application is completely decoupled through full automatic configuration and real movement. What is virtualization? Virtualization is the basic rule for decoupling infrastructure services from physical resources of operational services. The services we want to use (such as computing and network) are not described, identified, or strictly bound to any physical resources. Instead, a service is describe

Libvirt (http://libvirt.org/) is a good toolkit for virtualization environment management. The core is implemented in c, but APIs are called in different languages. The official website is described as follows: Libvirt is: A toolkit to interact with the specified alization capabilities of recent versions of Linux (and other OSes), see our project goals for details. Free software available under the GNU Lesser General Public License. A long term stable C API A set of bindings for common

This article mainly to give you detailed Cisco VN-LINK network services, so how to solve the network challenges of virtualization? How can we enhance the security of VMS? This article provides detailed answers. Cisco is working with VMware to launch the next-generation server virtualization network technology. Cisco®By integrating hypervisor, VM, network, and storage, VN-Link improves the mobility of virtual machines (VMS. Cisco VN-Link provides a con

the data center that requires verification and storage, and the price for running virtual machines, virtual application software, and services that provide actually running application software is also more expensive, stanley said, Enterprises that are used for a large number of users are increasingly demanding virtualization. These users are running resource-intensive applications and need high-level security and data center quality availability and backup. Song said. The IT department can all

In the Red Hat program, VMware became another target for them. Red Hat, which has always been focusing on Linux, is constantly strengthening its virtualization management software so that it will take a favorable position in the future competition with VMware. In last November, two months after RHEL5.4 was released, RedHat released its RedHatEnterpriseVirtualizationforServers (REV) bare-metal hypervisor solution. Rev with built-in KVM Virtualization I

. If the library is missing, you should continue to add the installation-such as libvirt;1. Start xend first;2. connect to connect xen in virt-manager;3. If an error occurs, the possible causes are as follows:1) xend is not started; or xend is incorrectly configured.In the/etc/xen/xend-config.sxp file, enable (xen-api-server (unix), (xend-http-server yes) /(xend-unix-server yes) --- enable one of the two servers;2) libvirt library is not installed successfully-virt-manager is mainly used to moni

Virtualization analysis virtual machine (VM) in Ubuntu is a computer running on the virtual layer, usually called hypervisor. It does not really exist, but it can work like a real computer. The virtual layer running on the virtual machine determines the virtual interface of the virtual machine...
