Xen Project Development Update
summary
Xen 4.3 introduces a formal release coordinator role and a tighter release process (feature freeze → code freeze → ~six‑week RC cycle); 4.3 slips ~3 weeks due to coordinated security disclosures. Work in 4.4 targets a six‑month cadence and concrete features: EFI boot via zen.efi with grub2 workarounds, experimental PVH support, non-udev scripts to let non‑Linux driver domains run, block improvements (persistent grants and indirect descriptors), FreeBSD PV/PVH ports, and planned per‑vCPU NUMA affinity — most items are implemented or staged but several remain tentative.
