QEMU has officially released version 10.2.0, showcasing a wealth of improvements and updates. This latest iteration results from collaboration among over 188 authors contributing more than 2300 commits, reflecting a robust community effort. Users can access the updated software and comprehensive changelog detailing all changes on QEMU's dedicated download page.
Among the notable enhancements, QEMU 10.2.0 introduces improved FreeBSD host support, specifically for 9pfs shared filesystems. The release also features a groundbreaking live update capability through the 'cpr-exec' migration mode, which efficiently manages resource use during updates while preserving existing states. Performance is notably enhanced by adopting io_uring for the core virtualization loop, promising a smoother experience across various applications.
User-mode emulation has received significant upgrades, resulting in a more refined operation due to numerous fixes. On the ARM emulation front, new CPU feature support has been added, including FEAT_SCTLR2, FEAT_TCR2, and FEAT_LSE128, along with new and improved board models like AST2600 and xlnx-zynqmp.
Additionally, HPPA emulation has been expanded to support the HP 715/64 workstation and the NCR 53c710 SCSI controller, with contributions from the community. PowerPC users benefit from new machine combinations such as PowerNV11 and PPE42, along with enhanced debugging capabilities through the FADUMP feature. RISC-V emulation has received various updates aimed at resolving longstanding issues, while s390x performance has been optimized with a refined virtio-pci irqfd setup.
In summary, QEMU 10.2.0 represents a significant step forward in virtualization technology, enhancing support for multiple architectures, improving performance, and streamlining user experience. Users are encouraged to explore the detailed changelog to fully appreciate the breadth of changes and enhancements made in this version. Future updates are anticipated, continuing the momentum of innovation and community-driven development
