Linux Foundation: Xen 4.11 and Hyperledger Global Forum

  • Xen 4.11 Improves Server Virtualization with PVH

    The open source Xen Project, which is hosted as a Linux Foundation effort, issued its first major release of 2018 on July 10.

    The Xen Project Hypervisor 4.11 release comes after months of development, and follows the 4.10 update that became available at the end of 2017. Xen 4.10 included some initial support for PVH (Paravirtualization Hardware), which has been further extended in the 4.11 update.

  • ​Re-engineering Xen: The important open-source hypervisor gets remodeled

    Xen is open-source royalty. This hypervisor, which runs and manages virtual machines (VMs), powers some of the largest clouds. You know their names: Amazon Web Services (AWS), Tencent, Alibaba Cloud, Oracle Cloud, and IBM SoftLayer. It's also the foundation for VM products from Citrix, Huawei, Inspur, and Oracle. But, with the release of its latest edition, Xen Project Hypervisor 4.11, there are major changes under the hood.

  • Xen 4.11 debuts new ‘PVH’ guest type, for the sake of security

    The Xen Project has released version 4.11 of its hypervisor.

    As we reported last week, it’s more than a month late, but the projects leaders thinks it is worth the wait because this release delivers on an ambition to “create a cleaner architecture for core technology, less code and a smaller computing base for security and performance.”

    A big part of delivering on that is increased use of PVH – a type of virtualization that Xen reckons blends the best of paravirtualization (PV) and Hardware Virtual Machines (HVM). PV virtualizes hardware so a guest can offer kit not found on its host, but doesn’t use virtualization extensions in silicon. HVM can use those extensions and therefore offers each VM isolated emulated hardware.

  • Last Chance to Speak at Hyperledger Global Forum | Deadline is This Friday

GCC 8.3 Released and GCC 9 Plans

  • GCC 8.3 Released
    The GNU Compiler Collection version 8.3 has been released. GCC 8.3 is a bug-fix release from the GCC 8 branch containing important fixes for regressions and serious bugs in GCC 8.2 with more than 153 bugs fixed since the previous release. This release is available from the FTP servers listed at: http://www.gnu.org/order/ftp.html Please do not contact me directly regarding questions or comments about this release. Instead, use the resources available from http://gcc.gnu.org. As always, a vast number of people contributed to this GCC release -- far too many to thank them individually!
  • GCC 8.3 Released With 153 Bug Fixes
    While the GCC 9 stable compiler release is a few weeks away in the form of GCC 9.1, the GNU Compiler Collection is up to version 8.3.0 today as their newest point release to last year's GCC 8 series.
  • GCC 9 Compiler Picks Up Official Support For The Arm Neoverse N1 + E1
    Earlier this week Arm announced their next-generation Neoverse N1 and E1 platforms with big performance potential and power efficiency improvements over current generation Cortex-A72 processor cores. The GNU Compiler Collection (GCC) ahead of the upcoming GCC9 release has picked up support for the Neoverse N1/E1. This newly-added Neoverse N1 and E1 CPU support for GCC9 isn't all that surprising even with the very short time since announcement and GCC9 being nearly out the door... Arm developers had already been working on (and landed) the Arm "Ares" CPU support, which is the codename for what is now the Neoverse platform.
