Welcome to Linux-VServer.org Linux-VServer provides virtualization for GNU/Linux systems. This is accomplished by kernel level isolation. It allows to run multiple virtual units at once. Those units are sufficiently isolated to guarantee the required security, but utilize available resources efficiently, as they run on the same kernel. This site contains information relating to the use and development of virtual servers based on Linux-VServer. This particular virtual server model is implemented through a combination of "security contexts", segmented routing, chroot, extended quotas and some other standard tools. Note: If this isn't what you are looking for, maybe Linux Virtual Server is.
Building and Promoting a Linux-based Operating System to Support Virtual Organizations for Next Generation Grids (2006-2010). The emergence of Grids enables the sharing of a wide range of resources to solve large-scale computational and data intensive problems in science, engineering and commerce. While much has been done to build Grid middleware on top of existing operating systems, little has been done to extend the underlying operating systems to enablee and facilitate Grid computing, for example by embedding important functionalities directly into the operating system kernel.
What is virtual server? Virtual server is a highly scalable and highly available server built on a cluster of real servers. The architecture of server cluster is fully transparent to end users, and the users interact with the cluster system as if it were only a single high-performance virtual server. Please consider the following figure.
This is the collection of Linux-related tips and tricks, mostly administration and configuration that helps to integrate Linux system into Windows office environment.
Need to monitor Linux server performance? Try these built-in command and a few add-on tools. Most Linux distributions are equipped with tons of monitoring. These tools provide metrics which can be used to get information about system activities. You can use these tools to find the possible causes of a performance problem. The commands discussed below are some of the most basic commands when it comes to system analysis and debugging server issues such as: Finding out bottlenecks. Disk (storage) bottlenecks. CPU and memory bottlenecks. Network bottlenecks.
"A (growing) collection of on-line wizards - for creating complex linux configuration files and scripts using simple web-enabled point-and-click methods. LinWiz://SimpleFirewall was the first of these - launched in March 2003, now replaced by LinWiz://PersonalFirewall and LinWiz://ServerFirewall."
"ParallelKnoppix is a modified Knoppix live CD designed for use in creating HPC clusters. You can start up PK on multiple nodes to run a cluster, and customize PK to add or remove applications. "
"OpenSSI is an open source single-system image clustering system. It allows a collection of computers to be treated as one large system, allowing applications running on any one machine access to the resources of all the machines in the cluster. [2] [3]"
"The OpenSSI project is a comprehensive clustering solution offering a full, highly available SSI environment for Linux. Goals for OpenSSI Clusters include availability, scalability and manageability, built from standard servers. Technology pieces include: membership, single root and single init, cluster filesystems and DLM, single process space and process migration, load leveling, single and shared IPC space, device space and networking space, and single management space."
"Linux Explorer ( LINUXexplo ) is a script that collects software and hardware information about a linux server for support purposes, similar to the Solaris explorer ( SUNWexplo ) , Redhat's "sysreport" and SuSE's "siga" script. The script is designed to collect information about a server to help service departments support linux and have a common set of scripts for collecting information about linux no matter what distro users are using. The information is stored in seperated directories, once all the information has been collected it then tar's up those directories into a single gzip tar file which can then be attached to an email for your support organization or copied to a remote server for safe keeping. "
G95 is a stable, production Fortran 95 compiler available for multiple cpu architectures and operating systems. Innovations and optimizations continue to be worked on. Parts of the F2003 standard have been implemented in g95.
Cloud computing with Linux thin clients For embedded Linux engineers and aficionados, one exciting aspect of cloud computing is the sudden interest in thin Linux clients. Explore cloud computing from a Linux perspective and discover some of the most innovative and popular Linux-based solutions—with a particular view toward Linux thin clients and environmentally beneficial options.
netboot.me is a service that allows you to boot nearly any operating system or utility on any computer with a wired internet connection - without having to know ahead of time what you'll want to boot. Once you can netboot.me, you never need to update your boot disk again! netboot.me works through the magic of netbooting. There are a number of ways to boot a computer with netboot.me. The simplest is to download a bootable image and burn it to a CD, USB memory stick, or floppy disk. Boot off it on any networked computer, and it will automatically fetch the latest boot options from netboot.me and let you choose from dozens of installation, recovery, testing, portable desktop and other tools. You can also start netboot.me from any computer running gPXE, or from any netbootable computer with some simple tweaks to your DHCP server.
Our objective is to let users boot their machines with bare minimal requirements on their side, and we will handle most of the problem that you may face in booting. All that user needs is Internet connectivity and a small program (gpxe) to boot the machine. This gpxe program provides network booting facility. You can download these program from our site (available at Downloads section). Also, you can find a list of distributions and tools that can be booted with BKO here. Your small 56KB gpxe program can boot any of these options!

The new PERC 5 and PERC 6 RAID controllers use SAS (Serial Attached SCSI), and a new driver, megaraid_sas. The new SAS 5 and SAS 6 non-RAID controllers use a new driver, mptsas, part of the mptfusion driver family. Both drivers are included in kernel.org 2.6.x kernels, and have been backported to the RHEL3 2.4.21-x kernels.
