Free xen software for linux

XenMan is an intuitive GUI based Xen management tool covering all phases of the operational lifecycle.

XenMan should prove valuable to both Xen administrators and those seeking an introduction to Xen virtualization management.

When you start XenMan the first time, it will prompt you with a dialog box requesting you to specify.

Disk Location : The Doms can have disks supported by files in a file system. This is the directory where the disks for the doms would get created. Choose a directory with enough disk space. (few GB)

Snapshot Location : Xen supports saving a state of a running Virtual Machine and restoring it at a later time. The snapshot location is default directory where snapshot of running virtual machines would be stored. Again, choose a directory with enough disk space.(few GBs)

DTC-Xen is a Xen dom0 application and SOAP server (with authentication and SSL) through which a Domain Technologie Control (DTC) Web hosting panel can be connected to manage your VMs.
It supports remote start, shutdown, and destroy of your virtual machines, as well as SSH login in the physical console (with the ability to remotely change the SSH password).
DTC-Xen also displays CPU and network graphs that can be used to analyse the performance of your virtual machines.
Enhancements:
- There was a bug in the calculation of the MAC address when calling changeBSDKernel to be able to change the kernel between NORMAL and INSTALL.
- Its now resolved.
- Be sure also to update DTC to the latest CVS version.

Xenoppix is a Knoppix-based live DVD distribution with Xen, a virtual machine monitor.
Xenoppix sets up device drives using autoconfig function of KNOPPIX and enables to boot a guest OS on Xen. X window System is prepared by KNOPPIX and GUI of GuestOS is mapped to the X11 using VNC full-screen mode. it looks GuestOS boots standalone.
The guest OS can work as a server because it gets IP address from external DHCP with VIF-Bridge of Xen.
Xenoppix(Xen 2.0.6) 1ncludes 2 Guest OSes; NetBSD and Plan9 and Xenoppix(Xen3.0) includes Xenoppix(KNOPPIX) itself.
Enhancements:
- Xenoppix (Xen3.0.2 + KNOPPIX 5.0.1) CD is released. It uses isolinux + mbootpack instead of GRUB, because the combination expands bootable machines. It enables Xen to boot on EFI (iMac CoreDuo). LCAT (Live CD Acceleration Toolkit) is applied to make fast boot. It was effective on Dom0, DomU and HVM.

xenConsole is a curses-based tty/console monitor for Xen 2.0, basically presenting the output from xm list in a full-screen interface with additional domain information from SNMP, colours and somewhat realtime updates.
Main features:
- Xen/domain/host information shown:
- Most output from xm list
- Load averages for individual domains, if available
- Uptime for individual domains, if available
- CPU & memory consumption shown as percentages for each domain
- Calculated total CPU busy/idle times/percentages
- Total Xen host CPU load is indicated in various ways
- Continously updates screen automatically
- Full screen application, colourized
- Easy to use, type q to quit

Fedora Linux brings you a powerful Linux operating system which is built from open source software. The Fedora Project is an openly-developed project designed by Red Hat, open for general participation, led by a meritocracy, following a set of project objectives.

The goal of The Fedora Project is to work with the Linux community to build a complete, general purpose operating system exclusively from open source software. Development will be done in a public forum. The project will produce time-based releases of Fedora Core about 2-3 times a year, with a public release schedule.

The Red Hat engineering team will continue to participate in building Fedora Core and will invite and encourage more outside participation than in past releases. By using this more open process, we hope to provide an operating system more in line with the ideals of free software and more appealing to the open source community.

Major Features:

1. Support for the PowerPC (PPC) architecture.
2. GCC 4.0
3. GNOME 2.10
4. KDE 3.4 includes new accessibility features. You can manage these new features in KDS Control CenterRegional & AccessibilityAccessibility.
5. Native Eclipse 3.1M6 (part of a free Java stack)
6. MySQL 4.1
7. PHP 5.0
8. Xen 2 (virtualization to run multiple versions of an OS)
9. GFS 6.1-0.pre22 (cluster file system)
10. Evince 0.2.1 (universal document viewer)
11. GDM 2.6 Includes early login capability
12. SELinux This release includes coverage for 80 new daemons by the targeted policy. There are changes to the handling of Booleans. The targeted policy is enabled by default.

rinse software was born out of a frustration with the currently available solutions for installing minimal copies of RPM-based distributions.
The need to perform simple chroot() installations of other distributions is not common, but the ability to do such a thing is very useful when it comes to testing new tools, and working towards the creation of new Xen guests.
The following distributions are supported:
- Centos 4 & 5
- Fedora Core 4, 5, 6 & 7
I plan to support OpenSUSE in the near future.
Enhancements:
- This is primarily a bugfix release, which restores the ability to install new distributions of Centos 4 & 5.

RMoX is an experimental/research occam-pi/CSP based operating-system for (currently) Pentium based PCs.

CSP provides a solid foundation for describing and reasoning about parallel systems and their interactions.

The occam-pi language is an enhanced version of occam (based on CSP), that adds ideas from the pi-calculus to provide a dynamic and flexible environment for building such concurrent systems.

Traditional occam was designed for Transputers (as developed by Inmos Ltd. and later SGS Thompson, now ST Microelectronics), which had a very finite memory, and no provision for features such as virtual memory (although the T9000 did provide a limited form of fault/memory protection). Transputers were primarily targetted at embedded-systems and therefore the use of such features would have been limited (especially considering the silicon cost).

The use of occam on modern computing systems has motivated substantial language development -- both at the language level and in the capabilities of the run-time system. As a result, occam-pi now provides support for facilities such as: data, channel and process mobility; multi-level process priority; extended synchronisation; and numerous others.

Whilst occam-pi is sufficient to develop many components of an operating-system, some of the more architecture-specific low-level operations remain tricky (and perhaps not best done in occam-pi). RMoX contains various "base-layers", one is selected depending on how you wish to use RMoX (e.g. user-mode in the host OS, or standalone).

Any hardware interaction is performed either by RMoXs device-drivers or the "base-layer". The base-layer provides an abstract interface to the hardware and can be changed depending on the desired use of RMoX.

The main functions of the base-layer are to provide the bootstrap, discovery and initialisation of certain hardware (e.g. the MMU), access to physical memory, interrupts and IO/memory-mapped devices. The various base-layers are:
Minlinux base-layer: this is a stripped-down version of the Linux kernel (2.4 series) that essentially replaces the traditional "init" task with the RMoX system. This replaces the Flux OSKit used previously.

Linux26 base-layer: this is a minimal configuration and wrappers for Linux 2.6, that loads the RMoX system as a module when booted (unconditionally transferring control to it). This approach is slightly cleaner than the minlinux base-layer as it does not require any modifications to the Linux 2.6 kernel tree.

Raw base-layer: this is an experimental base-layer written in assembler that performs basic initialisation before transferring control to RMoX.

User-mode base-layer: this provides a hardware abstraction for running RMoX in an existing Linux system as a normal user-mode application. This approach is particularly useful for debugging.

The run-time KRoC/CCSP kernel provides the scheduling and communication routines for occam-pi processes. This is essentially the same run-time kernel as used in KRoC/Linux, called CCSP. The version of CCSP currently in use is from pre-releases of the next KRoC/Linux version (1.4.0). Although the RMoX and "normal" versions of CCSP are built from the same source tree, what actually gets compiled is quite different (if RMoX is being built for non-user-mode; user-mode RMoX will get the standard KRoC run-time system).

Eventually we may do away with the Linux flavoured base-layers entirely, using the more specialised "raw" base-layer instead (largely in the interests of keeping the resulting system small). However, using a Linux base-layer makes much easier the task of machine startup -- in particular dealing with any hardware anomalies that the Linux community has already catered for (typically laptop computers). Another future possibility is a low-level infrastructure that sits on top of Xen, allowing RMoX to be run alongside other Xen-ported systems (primarily Linux, Windows-XP and Plan9).

Cobbler project is a provisioning configuration tool that enables administrators to rapidly set up environments for (simultaneously) provisioning PXE, installing Xen, and re-provisioning existing machines.
Set up of a PXE server, once a very manual process, is now greatly simplified. Cobbler also enables integrating Xen into a PXE provisioning infrastructure.
The application is designed for managing the provisioning of 1000s of machines or only just a few. Extensive documentation is provided in the accompanying manpages. Cobbler is easy to use and has an accompanying Python API.
Enhancements:
- This is a stable release that brings in Cobbler features developed since 0.4.0.
- These include dnsmasq integration support (DHCP+DNS), profile inheritance, qemu/KVM support for koan, XMLRPC interface upgrades, greater templating capabilities, control over install locations for virtual machines, support for importing distribution trees on external files, an enhanced trigger system, and numerous other improvements.
