[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] DRAFT: Xen 4.16 release blog post
Hello, Below is the starting draft for the Xen 4.16 release blog post. Note it has a bunch of XXX to be filled with new information. "Community Initiative Updates" listed projects is subject to changes as we gather more information. Once we have a more definitive draft (likely tomorrow if possible?) we should circulate it in order to gather a couple of Community Quotes. I'm Ccing Bertrand from Arm as he expressed Arm might be interested in providing a quote. --- XEN PROJECT SHIPS VERSION 4.16 WITH FOCUS ON IMPROVED PERFORMANCE SECURITY AND HARDWARE SUPPORT. NEW VERSION INTRODUCES ARM VIRTUAL PERFORMANCE MONITOR COUNTERS AND BROADER X86 HARDWARE SUPPORT. COMMUNITY INITIATIVES, INCLUDING FUNCTIONAL SAFETY AND VIRTIO, CONTINUE TO PROGRESS. The Xen Project, an open source hypervisor hosted at the Linux Foundation, today announced the release of Xen Project Hypervisor 4.16, which introduces a variety of features allowing for improved performance, security, functionality and hardware support. The Xen Project community continues to be active and engaged, with a wide range of developers from many companies and organizations contributing to this latest release. Additionally, community-wide initiatives, including Functional Safety and VirtIO for Xen, continue to make valuable progress. XXX: "Xen Project continues to be a mature, open source hypervisor well suited for enterprise use cases that require security and high levels of performance. In addition to the incredible work that went into this release, I’m also pleased with the multiple community initiatives the Xen Project continues to drive forward and contribute to." XXX: replace with something new Notable Features * Miscellaneous fixes to the TPM manager software in preparation for TPM 2.0 support. * Increased reliance on the PV shim as 32bit PV guests will only be supported in shim mode going forward. Such change reduces the surface of attack in the hypervisor. * Increased hardware support by allowing Xen to boot on Intel devices that lack a Programmable Interval Timer. * Cleanup of legacy components by no longer building QEMU Traditional or PV-Grub by default. Note both projects have upstream Xen support merged now, so it is no longer recommended to use the Xen specific forks. * Improved support for the Gitlab automated tests: 32bit Arm builds and full system tests for x86. * Initial support for guest virtualized Performance Monitor Counters on Arm. * Improved support for dom0less mode by allowing the usage on Arm 64bit hardware with EFI firmware. * Improved support for Arm 64bit heterogeneous systems by leveling the CPU features across all cores in order to improve big.LITTLE support. Community Initiative Updates Functional Safety Update XXX: to be provided VirtIO drivers for Xen: XXX: to be provided RISC-V Port: XXX: to be provided Community Quotes XXX: to be provided * AMD * Citrix * EPAM * SUSE * Vates * Xilinx * Arm? * Amazon/EWS? About the Xen Project Xen Project software is an open source virtualization platform licensed under the GPLv2 with a similar governance structure to the Linux kernel. Designed from the start for cloud computing, the Project has more than a decade of development and is being used by more than 10 million users. A project at The Linux Foundation, the Xen Project community is focused on advancing virtualization in a number of different commercial and open source applications including server virtualization, Infrastructure as a Services (IaaS), desktop virtualization, security applications, embedded and hardware appliances. It counts many industries and open source community leaders among its members including Amazon Web Services, Arm, Bitdefender, Citrix, EPAM Systems.
