The overall objective of the XtreemOS project is the design, implementation, evaluation, and distribution of a grid operating system (called XtreemOS) with native support for virtual organizations (VO). XtreemOS is capable of running on a wide range of underlying platforms, from clusters to mobiles. It is based on Mandriva Linux, with support to come for other distributions later.
neko-install-cd is a development tool for modifying System Rescue CD images. It can also perform many other operations. It has a simple interface with excellent inline help. Operations it can perform include: booting your modified image in a virtual machine, burning the original or modified image to a USB drive, creating patch sets from your modifications (using aufs or built-in helper scripts). All of these operations can be performed directly from your Linux distribution, without having to first boot into the system rescue CD as with the system rescue CD equivalents.
filter_evdev creates a virtual input device from a physical input device. It provides anytime configuration of positive, negative, or custom acceleration or sensitivity for each axis, or remapping axes or buttons as requested, e.g. inverting the two main mouse buttons or making the middle button act as the right button. Configuration can be dynamically changed by text commands sent to a UNIX socket. Commands apply to specific axes, buttons, or keys when moved in specified value ranges, and consist of custom arithmetic operations.
xNBD is yet another NBD (Network Block Device) server program, which is fully compatible with the NBD client driver in the Linux kernel. In comparison with the original NBD server, it provides possibly better I/O performance by using mmap(), concurrent access from multiple clients, distributed Copy-on-Write disk, and live storage migration for virtual machines.
topvhost is a curses-based display of virtual host activity on a Web server. The display is created by monitoring a collection of server log files to show update time, update count, and selected fields from the last record of each file in a top-like presentation which can be sorted by last update time, update count, or domain name. Log file format and display columns are configured using an extension of the Apache LogFormat syntax. The collection of associations between domain name and log file is specified either by direct enumeration or a file system glob() pattern in those cases where the domain name is part of the log file path. These details are saved in an INI format configuration file in the user's home directory.
