Kernel-based virtual machine http://www.aliyun.com/zixun/aggregation/13883.html "> Virtualization technology began to apply early in the Linux 2.6.20 kernel in 07, and over time, KVM Virtualization is the most widely used virtualization platform for Linux systems, and Ubuntu, Fedora applications KVM, and even Red Hat Enterprise Linux also uses KVM, applied to include Citrix Systems Inc.

KVM (kernel-based Virtual http://www.aliyun.com/zixun/aggregation/39569.html ">machine") http://www.linux-kvm.org /, kernel based virtual machines, with QEMU (processor virtual software), require CPU-enabled virtualization (and open virtualization options in the BIOS), more than 80% more efficient than physical machines. In addition, it is for s ...

Open source technology has begun to deeply affect the world of cloud computing. There are two main reasons: first, open source software is essentially free, and it is generally not affected by proprietary software copyright models. 　　Many proprietary software vendors, such as Microsoft and Oracle, are trying to maintain outdated and expensive license patterns, even though this pattern has hampered the flexibility of virtualization and cloud computing. Conversely, some open source tools are having a huge impact on the public cloud: Linux and Xen, for example. In addition, there are some other important open source tools also for users ...

Editor's note: As the two main open source cloud platform, OpenStack and cloudstack each have advantages. Cloudstack installation and deployment are very convenient, the OpenStack framework is relatively open and flexible, can be customized according to user needs convenient development and customization. In this paper, the blogger through its own OpenStack building company's private cloud platform of actual combat experience, OpenStack implementation of private cloud landing needs to comb, synthesize personal views and evaluation and share with readers. Work for some time ago, based on Openst ...

When looking for open source cloud computing service providers, companies with strong development capabilities or specific business applications tend to routinely avoid commercial cloud computing service providers. Open source cloud computing platforms such as Eucalyptus, OpenStack and abiquo are expected to succeed in building private cloud computing opportunities for companies. But some problems remain, such as how the Open-source cloud services provider can reflect its value. Who will pull the top? Can the Eucalyptus system win in the brutal competition with OpenStack?
