“Among the virtualisation solution’s new features are a revised
XL tool stack, the Credit2 scheduler designed for very large
systems and latency-sensitive workloads, support for more than 255
processors, EPT/VTd 1GB/2MB super pages, and the Advanced Vector
Extension (AVX) for new x86 CPUs (SSE5).“Also included is a new Memory Access API which allows
developers to integrate third-party security solutions into Xen’s
virtualised environments. Furthermore, the developers note that
automated regression tests now provide even better software
stability. “
