Dhowr maalmood ka hor waxaan halkan ku shaacinay barta warka sii deynta nooca cusub ee Sanduuqa Virtual 6.1, kaas oo la yimaada warar kala duwan iyo gaar ahaan taageerada Linux 5.4. Hadda Waxaa la joogaa waqtigii lagu dhawaaqi lahaa daahfurka nooca cusub ee QEMU 4.2, taas oo beddel fiican u ah VirtualBox iyo VMware.
Kuwa aan aqoon u lahayn QEMU, waa inaad ogaataa in kani yahay softiweer mashiinka kumbuyuutareedka bilaashka ah, kaas oo ku dayan kara processor-ka iyo guud ahaan qaab dhismeed ka duwan haddii loo baahdo. Adiga waxay u oggolaaneysaa socodsiinta hal ama in kabadan nidaamyada hawlgalka (iyo codsiyadiisa) gooni ahaanta iyada oo loo marayo kormeerayaal heer sare sida KVM iyo Xen, ama si fudud binaries, jawiga nidaamka qalliinka horay loogu rakibay mashiinka.
QEMU waxay awood u siineysaa hufnaanta iyada oo aan lagu dayan, haddii nidaamka martida uu adeegsado isla processor-ka nidaamka martida loo yahay, ama ku daydo qaab-dhismeedka x86, ARM, PowerPC, Sparc, processor MIPS1. Waxay ka shaqeysaa x86, x64, PPC, Sparc, MIPS, dhufto ee ARM iyo Linux, FreeBSD, NetBSD, OpenBSD, Mac OS X, Unix iyo Windows operating operating system.
Maxaa ku cusub QEMU 4.2?
Qaabkan cusub, Kooxda horumarinta ee QEMU waxay ku dhawaaqeen dhowr isbedel oo waaweyn, kaas oo QEMU 4.2 lagu bilaabay kuwo badan Horumarinta hufnaanta Linux.
Si kastaba ha noqotee, qaar waxyaabaha ugu muhiimsan cusbooneysiintan muuqaalada for emulator il furan ku dar casriyeynta ugu dambeysa ee dhammaan moodooyinka processor-ka hadda waxay leeyihiin Transactional Synchronisation Extensions (TSX) oo markii horeba naafo laga dhigay. Tan waxaa u sabab u nuglaanta dhowaan TSX Async Abort iyo Zombieload Variant Two.
Halka loogu talagalay KVM waxay ku darsatay awooda isticmaalka in ka badan 256 CPU iyo waxay bixiyaan taageero tilmaamaha SVD SIMD, iyo sidoo kale waxqabadka kudayashada oo la hagaajiyay iyadoo la adeegsanayo matoor code TCG
Waxqabadka kale ee hagaajinta ee QEMU 4.2 waa ka mid noqoshada maktabadaha dhawaanta ee Gcrypt iyo Nettle, halkaa QEMU hadda way isticmaali kartaa qaabka XTS encryption maktabadda u gaar ah tanina waxay ku dambayn kartaa koror ballaaran oo ku yimid waxqabadka sirta AES-XTS, gaar ahaan haddii aad isticmaasho LUKS disk encryption markaad ka soconayso QEMU.
para NBD, darawalka balooggu wuxuu hadda taageeraa farsameyn wax ku ool ah Akhriso codsiyada nuqul, oo lagu daray habeynta server ee la helay ee sawirada nuqulada nuqulada iyo hagaajinta guud / hagaajinta loogu talagalay macaamiisha NBD / adeegsiga serverka.
Wixii ah Emulator dhismeedka PowerPC leeyahay kartida ku dayashada tilmaamaha AWOODA9 mffsce, mffscrn iyo mffscrni. Mashiinnada lagu daydo, "powernv" ayaa lagu daray Taageerada qalabka nidaamka Homer iyo OCC SRAM.
In virio-mmio ayaa ku darsaday dabiici ahaan-socon kara heerka 2 iyo virio qeexan gaar ah 1,1 Nidaamka Safka ah ee loo yaqaan 'Virtual Packed Queue (virqueue') oo loogu talagalay is-weydaarsiga xogta aaladda I / O ee teknoolojiga ah ee qaab dufcaddeed
Isbadalada kale ee taagan ee noocaan cusub:
- Taageerada Intel AVX-512 BFloat16 (BF16) kordhinta.
- Waxqabadka ugufiican ee Generator Code Generator (TCG) kudayashada diirkja ARM.
- Darawalka xannibaadaha 'LUKS' wuxuu hadda taageeraa Falloc iyo qoondayn buuxda.
- QEMU waxay ku taageertaa ARM inay ku shaqeyso in ka badan 256 CPU.
- Taageero lagu daray nooca AST2600 ASPEED.
- Loogu talagalay ARM SVE (Kordhinta Vector Extensions) waxay hadda la jaanqaadeysaa martida KVM ee ARM SoC iyo kernel la taageeray.
- Taageerada Apple MacOS Hypervisor Framework (HVF) hadda waxaa loo arkaa mid deggan.
- Taageerada KVM ee tilmaamaha SIMD SVE ee ku saabsan SVE qalabka ku habboon.
- Taageerada jilitaanka ee mffsce, mffscrn iyo mffscrni POWER9 tilmaamaha.
- Mashiinka "powernv" wuxuu hada la jaan qaadayaa nidaamka Homer iyo OCC SRAM.
- Gudaha RISC-V khalad-sameeyaha wuxuu hadda arki karaa dhammaan qaab dhismeedka.
Si waxaad dooneysaa inaad waxbadan ka ogaato faahfaahinta sii deynta cusub ee QEMU 4.2, waad ka hubin kartaa QEMU.org.
Ugu dambeyntiina, kuwa xiiseynaya rakibidda nuqulkan cusub, waxay ka heli karaan nooca cusub dhexdiisa kanaalka rasmiga ah ee qaybintooda Linux, maadaama mashruucu caan ku yahay caan weyn. Kaliya isticmaal maareeyahaaga xirmada si aad uga rakibto terminal.
