XPDDS19: Bringing Xen to the Masses: The Story of Building a Community-driven Platform Around Xen


Published on

Xen is a very powerful hypervisor with a talented and diverse developers community. Despite the fact it's almost everywhere (from the Cloud to the embedded world), it can be difficult to set up and manage as a system administrator. General purpose distros have Xen packages, but that's just a start in your Xen journey: you need some tooling and knowledge to have a working and scalable platform.

XCP-ng was built to overcome those issues: by bringing Xen to the masses with a fully turnkey distro with Xen as its core. It's the logical sequel to the XCP project, with a community focus from the start. We'll see how it happened, what we did, and what's next. Finally, we'll see the impact of XCP-ng on the Xen Project.
