Welcome to the Xen4CentOS6 Project : First Release

CentOSLogoThe Xen4CentOS6 project is a collaborative effort between the Xen Project, the Citrix Xen development teams, the CentOS Project team, GoDaddy Cloud operations group and RackSpace Hosting to package, deliver and maintain a stable Xen hypervisor and its related tooling for CentOS-6, enabling CentOS-6/x86_64 to be used as a dom0, base platform to host Xen in paravirt and fullvirt deployment roles.

We have tried to ensure that existing tooling that users have in production written again xm/xend will continue to work, while also adding support for the newer xenlight (xl) layers. Most libvirt functions also continue to work on Xen4CentOS6 as they did on Xen3 CentOS5, enabling users to easily migrate their infra over from CentOS-5 to 6.

A second primary principle we are working against is to build and deliver a Linux Kernel based on the 3.4 LTS release, stabilised via testing, with enhanced Xen support as recommended by the Xen development team.

For more information about the Xen4CentOS project, technical notes and release notes, please refer to the following URLS:

We highly recommend reading through the Release Notes and the Quick Start guide before running your first install.

Keeping Up-to-date

We are working to integrate the Xen4CentOS release process, the update process and the announcements for security fixes into the regular CentOS systems respectively. Therefore it is highly recommended that users sign up to the CentOS-Announce list at so you can keep up with security and bug fix errata notices.

Getting Help

This complements the #centos-virt irc channel on For community driven aid, also look at the page on how you can put your problems and questions forward and request help for issues in the communities.

Contributions in all formats are welcome. Conversations about the Xen4Centos6 work happen on the centos-devel list ( at, so feel free to drop in and say hi.

What’s next

We have some very interesting things coming up in the near future including the full xapi stack, openstack integration, opennebula integration. And pre-build CentOS-5 and CentOS-6 images.

    This is great news! But I’m curious: Why based on Xen 4.2 and not on Xen 4.3?

  2. Lars Kurth says

    This is very simple : the work had started with Xen 4.2 and then slipped a little. We could have delayed the Xen4CentOS6 release even more, but it made more sense to get it out of the door and upgrade to Xen 4.3 later.
