Welcome to Darwin Streaming Server, the open source version of Apple’s QuickTime Streaming Server technology that allows you to send streaming media to clients across the Internet using the industry standard RTP and RTSP protocols. Based on the same code base as QuickTime Streaming Server, Darwin Streaming Server provides a high level of customizability and runs on a variety of platforms allowing you to manipulate the code to fit your needs.
Setting up Stable Xen Dom0 with Fedora
Xen – KVM – Linux – and the Community
KVM is a type-2 hypervisor built into the Linux kernel as a module and will ship with any Linux distribution moving forward as no work is required for the Linux distributions to add KVM. Having a virtualization platform built-in to the Linux kernel will be valuable to many customers looking for virtualization within a Linux based infrastructure; however these customers will lose the flexibility to run a bare-metal hypervisor, configure the hypervisor independent of the host operating system, and provide machine level security as a guest can bring down the operating system on KVM. Xen, on the other hand is a type-1 hypervisor built independent of any operating system and is a complete separate layer from the operating system and hardware and is seen by the community and customers as an Infrastructure Virtualization Platform to build their solutions upon.

Installing and Configuring Fedora Xen Virtualization
There are two common approaches to virtualization – full virtualization and para-virtualization. Full virtualization provides complete abstraction between the hardware and the guest operating system. In this scenario, the guest operating system is provided a complete virtual physical environment in which to run and, as such, is unaware that it is running inside a virtual machine. One advantage of full virtualization is that the operating system does not need to be modified in order to run in a virtualized environment. This means that proprietary operating systems such as Windows can be run on Linux systems.
Disadvantages of full virtualization are that performance is slightly reduced as compared to para-virtualization, and some virtualization platforms, such as Xen, require CPUs with special virtualization support built in (such as Intel-VT and AMD-V).

Building a Custom Kernel
If you are running Linux on a system with hardware or wish to use features not supported in the stock kernels, or perhaps you wish to reduce the kernel memory footprint to make better use of your system memory, you may find it necessary to build your own custom kernel.
I will get this right if it kills me.
The Linux Virtual Server Project – Linux Server Cluster for Load Balancing
What is the Linux Virtual Server?
The Linux Virtual Server is a highly scalable and highly available server built on a cluster of real servers, with the load balancer running on the Linux operating system. The architecture of the server cluster is fully transparent to end users, and the users interact as if it were a single high-performance virtual server. For more information, click here.

Installing Fedora Using PXE Images
Booting grub with the Fedora PXE vmlinuz/initrd images allows you to perform a network installation of Fedora over any existing linux distro, should you not be able to write to or boot from the conventional CD/DVD install media. A PXE netinstall can both be done locally, and with extra care, remotely using VNC. Both methods are explained in this HOWTO.

The Perfect Xen 3.0.1 Setup For Debian
This tutorial provides step-by-step instructions on how to install Xen (version 3.0.1) on a Debian Sarge (3.1) system.
Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called “virtual machines” or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers’ web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it’s more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.

This howto works for other distros as well.
I’ve gone this far without ever having to compile a kernel … until now. 🙂 Though the howto is a bit dated, I downloaded the latest xen distro here. (xen 4.1.1)
