Bringing Xen dom0 to CentOS-6
summary
Released Xen4CentOS (June 2013) provides a production path to run Xen 4 on CentOS‑6 by shipping a curated kernel 3.4 LTS with Xen patches (including block layer 2.5) and a migration workflow that preserves existing CentOS‑5 Dom0 tooling. Large hosts test at scale (one tested on a 30,000‑hypervisor cluster), estimated addressable base was ~750,000 CentOS‑5+Xen installs, and initial repo activity shows ~87,000 unique IPs. A migration script exists but is intrusive and risky; recommended approach is VM migration rather than in‑place Dom0 upgrade.
