[ANNOUNCE] Xen 4.1 released!

[ANNOUNCE] Xen 4.1 released!

[Keir Fraser]

The Xen team is pleased to announce the release of Xen 4.1.

The result of nearly 12 months of development, new features include:
 * A re-architected and improved XL toolstack replacing XM/XEND
 * Prototype credit2 scheduler designed for latency-sensitive workloads and
   very large systems.
 * CPU Pools for advanced partitioning.
 * Support for large systems (>255 processors)
 * Support for x86 Advanced Vector eXtension (AVX).
 * New Memory Access API enabling integration of 3rd party security
   solutions into Xen virtualized environments.
 * Many IOMMU fixes (both Intel VT-d IOMMU and AMD IOMMU).
 * Many toolstack and buildsystem fixes for Linux and NetBSD hosts.
 * Thirdparty libs: libvirt driver for libxl has been merged to upstream
   libvirt.
 * HVM guest PXE boot enhancements, replacing gPXE with iPXE.
 * Even better stability through our new automated regression tests.
