Today marks a new day as the Xen4CentOS6 project has made its way into the official CentOS repo.
After RHEL dropped support for Xen in EL6 in favour of their KVM equivalent, it’s meant cloud ops teams and developers alike were manually compiling packages or using third-party untrusted repos to launch their virtual infrastructure.
Thankfully, Xen can now be installed (cleanly) via Yum. This means its essentially just another RPM on your system, not a burden.
Shout out to the team at the Xen Hypervisor Project, GoDaddy and Rackpace for making this all possible.
