The move frees the project from a maintenance burden that developers had described as unsustainable.<\/p>\n\n\n\n<p>One clarification: the removal affects hosts (the systems running QEMU itself). Emulating 32-bit guest systems on a 64-bit host remains fully supported.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What&#8217;s New<\/h3>\n\n\n\n<p>Among the notable additions is a new accelerator called &#8220;nitro&#8221;, designed to run AWS Nitro Enclaves natively under QEMU. It&#8217;s useful for those who want to replicate AWS-compatible environments locally or manage isolated workloads without relying on the cloud. The MSHV and WHPX accelerators also see improvements, relevant for QEMU users on Windows or with Hyper-V.<\/p>\n\n\n\n<p>On the KVM front, this release introduces virtualization of CET (Control-flow Enforcement Technology) and adds reset support for dedicated virtual machines based on SEV-SNP and TDX, technologies used to isolate workloads in confidential computing environments.<\/p>\n\n\n\n<p>virtio-gpu gains support for native context drivers and the ability to assign a distinct resolution to each video output. TCG, QEMU&#8217;s internal code translator, now includes in-tree support for C++ plugins, useful for developers building analysis and debug tools. The NFS driver adds compatibility with libnfs v6, while curl and FUSE drivers receive various improvements, including asynchronous request handling for FUSE.<\/p>\n\n\n\n<p>ARM also sees notable updates: emulation of FEAT_ASID2 and FEAT_E2H0 extensions, TCG emulation of SME (Scalable Matrix Extension), and HVF acceleration of SME2 on macOS. x86 gains the Diamond Rapids CPU model.<\/p>\n\n\n\n    \n    <div class=\"yoota-fonte\">\n        <a href=\"https:\/\/www.qemu.org\/2026\/04\/22\/qemu-11-0-0\/\" target=\"_blank\" rel=\"nofollow noopener\" class=\"yoota-fonte-hit\">\n            \n            <span class=\"yoota-fonte-icon\" aria-hidden=\"true\">\n                <i class=\"ri-external-link-line\"><\/i>\n            <\/span>\n\n            <span class=\"yoota-fonte-content\">\n                <span class=\"yoota-fonte-label\">SOURCE:\/\/<\/span>\n\n                                    <span class=\"yoota-fonte-link\">\n                        qemu.org                    <\/span>\n                            <\/span>\n\n        <\/a>\n    <\/div>\n    \n    \n\n\n\n    \n    <div class=\"yoota-fonte\">\n        <a href=\"https:\/\/linuxiac.com\/qemu-11-0-released-with-dropped-32-bit-host-support\/\" target=\"_blank\" rel=\"nofollow noopener\" class=\"yoota-fonte-hit\">\n            \n            <span class=\"yoota-fonte-icon\" aria-hidden=\"true\">\n                <i class=\"ri-external-link-line\"><\/i>\n            <\/span>\n\n            <span class=\"yoota-fonte-content\">\n                <span class=\"yoota-fonte-label\">SOURCE:\/\/<\/span>\n\n                                    <span class=\"yoota-fonte-link\">\n                        linuxiac.com                    <\/span>\n                            <\/span>\n\n        <\/a>\n    <\/div>\n    \n    \n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>QEMU 11.0 removes support for 32-bit hosts, a maintenance burden described as unsustainable.
