xpds13: xenserver-core: what it is, how it is built and how to get involved - euan harris, citrix
DESCRIPTION
XenServer is open source and freely available, but it is packaged as an appliance image which must be installed on dedicated hardware. xenserver-core repackages the core components of XenServer so they can easily be built and installed on a standard Linux distribution. Its main goals are: * to make it easy to download, modify and build XenServer components, or just learn how they work; * to help upstream distributions to include up-to-date XenServer packages; * to provide an environment for experimentation. This talk will explain the motivations behind xenserver-core and how it relates to the open-sourcing of XenServer. For developers, it will cover how to get the code, how to build it and how to contribute back to the project. For packagers, it will explain the project's development and release processes and what an upstream maintainer can expect from it.TRANSCRIPT

How can I get involved?
