Linux Xen Kernel

This is a xenified version of the 2.6.18 Linux kernel, it recursively the patch for the recent ' Vmsplice ' root exploit (cve-2008-0600 )-along with statically linked Xen drivers. Submitted by:attila@ ...

On the EC2, I used the Rightscale ami as the V1 version of Centos5, which has a kernel version of 2.6.16. You can use the following methods to upgrade to 2.6.18. Because Amazon allows you to select the kernel version at startup, Amazon offers the latest kernel version of 2.6.18 (in fact, Rightscale is using Amazon's 2.6.18 kernel), so you can choose to use 2.6.18 kernel startup and then in ...

When you joined the Xen Summit last week, you heard the XCI (Xen Client Initiative) project (see Xen Cloud Platform (XCP)), Xen clients hypervisor:the Ultimate The "project is" to Define a standard framework for supporting service domain virtual Applian ...

What kind of virtualization technology to choose for the cloud computing platform will be a problem that cloud computing construction will face. This article compares and analyzes the architecture levels of the four mainstream virtualization technologies.

Virtualization is the first step toward the cloud, and, similarly, open source virtualization is the first step toward an open source cloud. Cloud computing offers products and solutions that revolve around the new delivery and consumption patterns of IT resources. The diversity of the cloud, the private cloud, the public cloud and the hybrid cloud, no matter which cloud has three key characteristics: virtualization, standardization and automation. So, what's a KVM? Can it meet the needs of the enterprise to the cloud? What's a KVM? KVM (kernel-based Virtual Machine) Source ...

Today continues our XCI project study, in how to analyze the Xen source article has said to the analysis Linux system this kind of big project first may start from makefile, then xci makefile what is different? Let's take a look at the following: Http://xenbits.xen.org/gitweb?p=xenclient/build.git;a=summary open the Makefile in the Project tree directory, which is typically the makefile under the root directory ...

September 23, virtualization technology for the Linux kernel Xen was given a hat-trick with 3 security vulnerabilities. Xen vulnerabilities can be jumped out of the virtual host environment (ultra vires), or read other user data, control the hypervisor itself (host). A remote attacker could exploit a vulnerability that could cause the host system to crash and deny service to legitimate users. Xen Vulnerabilities and impact range is not small, such as Amazon AWS Large-scale restart server-the entire repair cycle lasted 5 days (from September 25 7 o'clock in the afternoon to September 30 5 o'clock in the afternoon), impact ...

Today, open source firewalls are numerous. 　　This article will cover 10 of the most practical open source firewalls that fit your business needs. 1. Iptables Iptables/netfilter is the most popular command line based on firewalls. It is the safe line of defense for Linux servers. Many system administrators use it to fine-tune the server. The function is to filter packets from the network stack in the kernel, including: listing the contents of the packet filtering rule set, and executing fast because it only checks the header of the packet, and the administrator can ...

Cloud computing and storage transform physical resources, such as processors and storage, into scalable, shareable resources on the Internet (computing and storage as services). While virtualization is not a new concept, the sharing of physical systems through server virtualization does make resources much more scalable and much more efficient. Cloud computing enables users to access large scale computing and storage resources, and they do not have to know the location of those resources and how they are configured. As you would expect, Linuxreg;

This article takes you through virtualization, enumerates common virtualization software and virtualization architectures, and finally makes an introduction to kvm.
