Ngemuva kwezinyanga eziyisishiyagalombili zokuthuthuka, I-Xen 4.16 hypervisor yamahhala ikhishwe, inguqulo lapho izinkampani ezifana ne-Amazon, Arm, Bitdefender, Citrix kanye ne-EPAM Systems zibe nesandla ekuthuthukisweni kwenguqulo entsha.
Kulabo abangajwayelene neXen, kufanele ukwazi lokho ngumthombo ovulekile womshini wokuqapha womshini ithuthukiswe yiYunivesithi yaseCambridge. Inhloso yokuklama ukukwazi ukusebenzisa izimo ezisebenza ngokuphelele zezinhlelo zokusebenza ngendlela esebenza ngokuphelele kukhompyutha eyodwa.
Xen ihlinzeka ngokuhlukaniswa okuphephile, ukulawula izinsiza, ikhwalithi yeziqinisekiso zensizakalo nokufuduka kwemishini eshisayo ebonakalayo. Izinhlelo zokusebenza zingaguqulwa ngokusobala ukuze zisebenze i-Xen (ngenkathi igcina ukuhambisana nezinhlelo zokusebenza zomsebenzisi).
Lokhu kwenza ukuthi iXen ifinyelele ekusebenzeni okuhle okuphezulu. ngaphandle kokusekelwa okhethekile kwehadiwe. I-Intel yenze iminikelo eminingi kuXen engeze ukusekelwa kwezandiso zayo zokwakhiwa kweVT-X Vanderpool.
Lobu buchwepheshe ivumela amasistimu wokusebenza angalungisiwe ukuthi asebenze njengosokhaya ngaphakathi kwemishini ebonakalayo Xen, inqobo nje uma iseva ebonakalayo isekela izandiso ze-Intel VT noma i-AMD Pacifica.
Izici ze-Xen 4.16 Main
Kule nguqulo entsha ye-hypervisor kuqokonyiswe ukuthi ku Umphathi we-TPM, ehlinzeka ngama-chips abonakalayo okugcina okhiye be-cryptographic (vTPM), esetshenziswa ngesisekelo se-TPM evamile ebonakalayo (I-Trusted Platform Module), Ikhishiwe ukuze isekele ukucaciswa kwe-TPM 2.0.
Futhi se yengeze ukuncika okukhulu kungqimba lwe-PV Shim esetshenziselwa ukusebenzisa amasistimu e-paravirtualized guest (PV) angashintshiwe endaweni ye-PVH ne-HVM. Ngokuzayo, ukusetshenziswa kwe-32-bit paravirtualized guest systems kuyokwenzeka kuphela kumodi ye-PV Shim., okuzonciphisa inani lezindawo ku-hypervisor lapho kungaba khona ubungozi obunamandla.
Kubuye kuqhakanjiswe lokho izingxenye eziphelelwe yisikhathi zahlanzwa, iyeke ukuhlanganisa okuthi "qemu-xen-traditional" kanye nekhodi ye-PV-Grub ngokuzenzakalelayo (isidingo salezi zimfoloko eziqondene ne-Xen sinyamalele ngemva kokuba izinguquko ezihambisana ne-Xen zidluliselwe ku-QEMU ne-Grub eyinhloko).
Ngakolunye uhlangothi, singathola i- usekelo oluthuthukisiwe lwemodi ye-non-dom0, okuvumela ukuthi udlule ukuqaliswa kwemvelo ye-dom0 ngokuqala imishini ebonakalayo ngesikhathi sokuqala kweseva. Izinguquko ezenziwe zivumela ukuqaliswa kokusekelwa kwezinhlelo ze-64-bit ARM nge-firmware ye-EFI.
I ukwesekwa kwamasistimu e-ARM Amasistimu angu-64-bit heterogeneous asekelwe ku-big.LITTLE architecture, ehlanganisa ama-cores anamandla, kodwa adla amandla futhi angasebenzi kahle, kodwa ama-cores awonga amandla e-chip eyodwa.
Ngaphandle kwalokho, futhi ichweba le-RISC-V liyagqama, okuthi phakathi nalo mjikelezo wokukhululwa, kwenziwe umsebenzi obalulekile ngaphakathi ukuze kutholwe i-dom0 ukuthi iqalise ihadiwe ye-RISC-V, egxile ekwethuleni ukusebenza ukuze kuvunyelwe ukuphathwa kokuphazamisa, kanye nezinye izixhumi ezibonakalayo ezidingekayo ukuze kuqaliswe ikhodi yokuqala.
Kwezinye izinguquko okuvelele kule nguqulo entsha:
- Kwengezwe amandla okuqalisa kumadivayisi e-Intel ngaphandle Kwesibali Sesikhathi Esihlelekayo (PIT).
- Ezivakashini ze-ARM, usekelo lokuqala lwezibali zokuqapha ukusebenza luye lwasetshenziswa.
- Ukwesekwa okwengeziwe kwezingxenyekazi zekhompuyutha ngokuvumela i-Xen ukuthi iqale kumadivayisi e-Intel antula isibali-sikhathi sesikhashana esihlelekayo.
- Ukuhlanzwa kwezingxenye zefa lapho uyeka ukuhlanganisa i-QEMU Traditional noma i-PV-Grub ngokuzenzakalelayo. Qaphela ukuthi womabili amaphrojekthi ahlanganise ukwesekwa kwe-Xen phezulu komfula manje, ngakho ukusebenzisa izimfoloko eziqondene ne-Xen akusanconywa.
- Usekelo lokuqala lwezibali zokuqapha ukusebenza okubonakalayo kwesivakashi ku-Arm.
- Usekelo oluthuthukisiwe lwezinhlelo ze-64-bit Arm ezihlukile ngokulinganisa izindima ze-CPU kukho konke ukuze kuthuthukiswe ukwesekwa okukhulu.LITTLE.
Okokugcina Uma unentshisekelo yokwazi okwengeziwe ngayo, ungabonisana imininingwane ekulesi sixhumanisi esilandelayo. Ukukhishwa kwezibuyekezo zegatsha le-Xen 4.16 kuzohlala kuze kube uJuni 2, 2023 kanye nokukhishwa kokulungiswa kobungozi kuze kube umhla ka-2 Disemba 2024.
