Zimbalwa iintsuku ezidlulileyo ukukhutshwa kwenguqulelo entsha ye-QEMU 7.0 yabhengezwa, ekuvumela ukuba uqhube inkqubo eyakhelwe iqonga elilodwa le-hardware kwinkqubo enezakhiwo ezihluke ngokupheleleyo, umzekelo, ukusebenzisa isicelo se-ARM kwi-PC ehambelana ne-x86. Kwimowudi ye-virtualization kwi-QEMU, ukusebenza kwekhowudi yokubulawa kwekhowudi kwindawo engayodwa kufana nenkqubo ye-hardware ngenxa yokwenziwa ngokuthe ngqo kwemiyalelo kwi-CPU kunye nokusetyenziswa kwe-Xen hypervisor okanye imodyuli ye-KVM.
Ukutyhubela iminyaka yophuhliso, ukuxhasa ukulinganisa okupheleleyo kwi-architecture ye-14 ye-hardware yongezwa, inani lezixhobo ze-hardware ezifanisiweyo zadlula i-400. Ukulungiselela inguqulo ye-7.0, phezu 2500 utshintsho lwenziwa 225 abaphuhlisi.
Iimpawu ezintsha eziphambili ze-QEMU 7.0
Kolu guqulelo lutsha lwe-QEMU 7.0 oluvezwayo, i Intel AMX imiyalelo iseti inkxaso (Izandiso zeMatrix eziPhezulu) iphunyezwe kwi abaqhubekekisi beseva I-Intel Xeon ikhutshwe kwaye yongezwe kwi-emulator yoyilo lwe-x86. I-AMX ibonelela ngerejista entsha yesiko le-TMM "TILE" kunye nemiyalelo yokuguqula idatha kwezi rejista, njenge-TMUL (i-Tile matrix MULtiply) yophindaphindo lwe-matrix.
Olunye utshintsho olwahlukileyo kukuba ukuguquguquka kokugcinwa kwemifanekiso esebenzayo kuphuculwe inkqubo yangoku (i-snapshot yenziwe, emva koko ikopi-phambi-ubhale (CBW) icebo lokucoca lisetyenzisiwe ukuhlaziya ubume besnapshot, ukukopa idatha kwiindawo apho inkqubo yeendwendwe ibhalela kuzo). Ukukwazi ukufikelela kwi-snapshot kunye ne-backup akubonelelwanga ngokuthe ngqo, kodwa kunoko nge-snapshot ukufikelela kwisixhobo somqhubi wesixhobo.
I-ARM emulator yoomatshini be-'virt' yongeze inkxaso ye-virtio-mem-pci, Ubhaqo lwe-topology ye-CPU yendwendwe kunye nokusetyenziswa kwe-PAuth xa usebenzisa i-hypervisor ye-KVM ene-hvf iaccelerator, kunye nenkxaso eyongezelelweyo ye-PMC Flash OSPI kunye nokulinganisa umqhubi we-SLCR kumlingisi webhodi 'xlnx-versal-virt'.
I-emulator yoyilo I-RISC-V yongeza inkxaso ye-KVM hypervisor kwaye iphumeze iVector 1.0 izandiso zevektha, kunye nenkxaso yokulayisha i-OpenSBI (i-RISC-V Supervisor Binary Interface) iibhinari ezilinganisiweyo zoomatshini 'zespike' zongeziwe. Kumatshini wokulinganisa we-'virt', ukukwazi ukusebenzisa ukuya kuthi ga kwi-32 core processors kunye nenkxaso ye-AIA iphunyeziwe.
Ye- Olunye utshintsho ezibalaseleyo:
- I-emulator ye-architecture ye-HPPA inikezela ukuya kuthi ga kwi-vCPUs ye-16 kunye nesilawuli semizobo ephuculweyo ye-HP-UX VDE/CDE yendawo yomsebenzisi.
- Kongezwe ukukwazi ukutshintsha indlela yokuqalisa yezixhobo ze-SCSI.
- Inkxaso eyongeziweyo yokusebenzisa ukuya kuthi ga kwi-4 CPU cores, ukulayisha umfanekiso we-initrd wangaphandle, kwaye ngokuzenzekelayo ukuvelisa umthi wesixhobo sondoqo ovulelekileyo kwi-OpenRISC ye-architecture emulator yeebhodi 'zesim'.
- I-PowerPC yoyilo lwe-emulator yokulinganisa oomatshini be-'pseries' iphumeze ukukwazi ukuqhuba iinkqubo zeendwendwe phantsi kolawulo lwe-hypervisor ye-KVM enendlwane. Inkxaso eyongeziweyo yesixhobo se-spapr-nvdimm.
- Inkxaso eyongeziweyo ye-XIVE2 yokuphazamisa isiphazamisi kunye nabaphangi be-PHB5 be-'powernv' koomatshini abafanisiweyo, inkxaso ephuculweyo ye-XIVE kunye ne-PHB 3/4.
- Inkxaso yokwandiswa kwe-z15 (I-Miscellaneous-Instruction-Extensions Facility 3) yongezwe kwi-emulator ye-architecture ye-s390x.
- I-Classic TCG (i-Tiny Code Generator) isuse inkxaso yemikhosi ene-ARMv4 kunye ne-ARMv5 CPUs ezingaxhasi ukufikelela kwimemori engahambelaniyo kwaye ayinayo i-RAM eyaneleyo yokuqhuba i-QEMU.
- Inkxaso yeelebhile zokhuseleko kwimodyuli ye-virtiofs, esetyenziselwa ukuthumela inxalenye yenkqubo yefayile ukusuka kwindawo yokusingatha ukuya kwinkqubo yeendwendwe, iphuculwe.
- Ubuthathaka obulungisiweyo CVE-2022-0358, ekuvumela ukuba unyuse amalungelo akho kwisistim ngokwenza iifayile eziphunyezwayo kuluhlu olugqithiselwe ngee-virtiofs, ezizelinye iqela kwaye zixhotyiswe ngeflegi yeSGID.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo yotshintsho kunye nezinto ezintsha ezinikwe kolu guqulelo lutsha lwe-QEMU 7.0 ungajonga iinkcukacha kunye nokunye eli khonkco lilandelayo
