I f\u00f6rberedelsen av version 11.0.0 gjordes mer \u00e4n 2500 \u00e4ndringar av 237 utvecklare.     <\/p>\n<p>Nyckel f\u00f6rb\u00e4ttringar som lagts till QEMU 11.0:   <\/p>\n<ul>\n<li class=\"l\"> St\u00f6det f\u00f6r 32-bitars v\u00e4rdsystem har tagits bort, vilket f\u00f6rklarades som f\u00f6r\u00e5ldrat i april f\u00f6rra \u00e5ret i QEMU 10.0.

In AWS EC2, the Nitro Enclave technology allows nested isolated enclaves to run within a virtual machine, enabling work with confidential data while allocating part of its resources.\n<li class=\"l\"> St\u00f6det f\u00f6r virtualiseringsacceleratorerna MSHV (Microsoft Hypervisor) och WHPX (Microsoft Windows Hypervisor Platform Extensions) har f\u00f6rb\u00e4ttrats.\n<li class=\"l\"> When using KVM hypervisor (\"-accel kvm\"), support for Intel CET (Control-flow Enforcement Technology) virtualization extension has been provided for use in <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sv\/vps\/abuzoustojchivye-vps\/\"   title=\"virtuella maskiner\" data-wpil-keyword-link=\"linked\">virtuella maskiner<\/a> protection against exploits that utilize return-oriented programming (ROP \u2014 Return-Oriented Programming) methods.

Support for DRM contexts is enabled when using the new device virtio-gpu-gl with the option \"drm_native_context=on.\" Unlike Virgl and Venus contexts, which operate at the OpenGL and Vulkan API level, the DRM context is implemented at the Linux kernel's UAPI level.\n<li class=\"l\"> M\u00f6jlighet att anv\u00e4nda spr\u00e5ket C++ f\u00f6r att utveckla plugins till TCG (Tiny Code Generator) har lagts till.\n<li class=\"l\"> I blockdrivrutinen f\u00f6r NFS har st\u00f6d f\u00f6r byggnation med biblioteket libnfs 6 lagts till.\n<li class=\"l\"> The curl block driver has been updated with a \"force-range\" option to enforce the use of the HTTP \"Range\" header when downloading images without prior checking its support with a separate HEAD request.\n<li class=\"l\"> I blockdrivrutinen f\u00f6r FUSE har hanteringen av exportoperationer i synkront l\u00e4ge st\u00e4ngts av, vilket ledde till att starten av den virtuella maskinen blockerades tills andra FUSE-beg\u00e4rningar var behandlade. M\u00f6jlighet att anv\u00e4nda flera in-\/utg\u00e5ngstr\u00e5dar (iothread) vid export till FUSE har lagts till.\n<li class=\"l\"> The x86 architecture emulator has added support for Intel Diamond Rapids CPU (\"Xeon 7\").\n<li class=\"l\"> I emulatorn f\u00f6r ARM-arkitekturen har processorutvidgningarna FEAT_ASID2 och FEAT_E2H0 lagts till. I TCG (Tiny Code Generator) har emuleringen av utvidgningarna SME (Scalable Matrix Extension) implementerats.\n<li class=\"l\"> I emulatorn f\u00f6r HPPA-arkitekturen har st\u00f6d f\u00f6r emulering av 64-bitars CPU:er med 40- och 44-bitars adressrymden lagts till. Genom SeaBIOS-hppa 24 har PCI-kontrollern Astro initierats, vilket m\u00f6jligg\u00f6r anv\u00e4ndning av PCI-grafikkort p\u00e5 64-bitars system.\n<li class=\"l\"> I emulatorn f\u00f6r LoongArch-arkitekturen har m\u00f6jlighet till migrering av PMU (Performance Monitoring Unit) lagts till n\u00e4r hypervisorn KVM anv\u00e4nds. I TCG (Tiny Code Generator) har emuleringen av utvidgningarna LA v1.1, sc.q och llacq\/screl, samt instruktionerna FRECIP och DRECIP f\u00f6r att ber\u00e4kna inversa v\u00e4rden implementerats.\n<li

instruktionerna Zilsd, Zclsd, ZALASR och Smpmpmt implementerats.\n<li class=\"l\">  The s390 architecture emulator has gained support for booting from virtio-blk-pci devices and has implemented the emulation of the \"DIVIDE TO INTEGER\" instruction.\n<li class=\"l\"> A fix has been adopted that reduces the latency during fdmon (file descriptor monitoring) operation in \"aio=io_uring\" mode by
