Emva kweenyanga ezisibhozo zophuhliso, I-Xen 4.16 hypervisor yasimahla ikhutshwe, inguqulo apho iinkampani ezifana ne-Amazon, i-Arm, i-Bitdefender, i-Citrix kunye ne-EPAM Systems ziye zafaka isandla ekuphuhliseni inguqu entsha.
Kwabo bangaqhelekanga ngeXen, kuya kufuneka uyazi loo nto ngumthombo ovulekileyo wokujonga umatshini iphuhliswe yiDyunivesithi yaseCambridge. Injongo yoyilo kukwazi ukuqhuba imeko esebenzayo ngokupheleleyo yeenkqubo zokusebenza ngendlela esebenzayo ngokupheleleyo kwikhompyuter enye.
xen ibonelela ngokuzikhusela okukhuselekileyo, ulawulo lwezixhobo, umgangatho weenkonzo zokuqinisekisa kunye nokufuduka komatshini oshushu. Iinkqubo ezisebenzayo zinokuchazwa ngokucacileyo ukuqhuba iXen (ngelixa kugcinwa ukungqinelana nokusetyenziswa komsebenzisi).
Oku kwenza ukuba iXen ifezekise ukusebenza okuphezulu. ngaphandle kwenkxaso ekhethekileyo yezixhobo. I-Intel yenze igalelo kwiXen eyongeze inkxaso ye-VT-X Vanderpool eyandisiweyo.
Obu buchwephesha ivumela iinkqubo zokusebenza ezingatshintshiyo ukuba zisebenze njengezixhobo ngaphakathi koomatshini ababonakalayo Xen, okoko nje iserver ebonakalayo ixhasa i-Intel VT okanye i-AMD Pacifica yolwandiso.
I-Xen 4.16 Iimpawu eziNtsha eziPhambili
Kule nguqulo entsha ye-hypervisor ibonakaliswe ukuba ku Umphathi weTPM, ebonelela ngeetshiphusi zenyani zokugcina izitshixo ze-cryptographic (vTPM), ziphunyezwe ngokwesiseko se-TPM eqhelekileyo yomzimba (iModyuli yeQonga elithembekileyo), Ifakwe amaphecana ukuxhasa ngakumbi inkcazo ye-TPM 2.0.
Kwakhona se wongeze ukuthembela ngakumbi PV Shim umaleko esetyenziselwa ukuqhuba iinkqubo zeendwendwe ezingalungiswanga (PV) kwi-PVH kunye ne-HVM. Kwixesha elizayo, ukusetyenziswa kwe-32-bit ye-paravirtualized yeesistim zeendwendwe kuyakwenzeka kuphela kwimo ye-PV Shim., eya kunciphisa inani leendawo kwi-hypervisor apho kunokubakho ubuthathaka obunokwenzeka.
Kuyacaciswa ukuba izinto eziphelelwe lixesha zacocwa, yayeka ukuqokelela "qemu-xen-traditional" kunye nekhowudi ye-PV-Grub ngokungagqibekanga (isidingo sezi folokhwe ze-Xen ezikhethekileyo zanyamalala emva kokuba utshintsho oluhambelana ne-Xen luthwalwe kwi-QEMU kunye ne-Grub engundoqo).
Kwelinye icala, sinokuyifumana inkxaso ephuculweyo ye-non-dom0 mode, ekuvumela ukuba udlule ukuphunyezwa kwemeko-bume ye-dom0 ngokuqala oomatshini benyani kwinqanaba lokuqala lokuqalisa komncedisi. Utshintsho olwenziweyo luvumela ukuphunyezwa kwenkxaso ye-64-bit ye-ARM iinkqubo kunye ne-firmware ye-EFI.
I inkxaso kwiinkqubo ze-ARM Iinkqubo ze-64-bit heterogeneous ezisekelwe kwi-big.LITTLE architecture, edibanisa amandla, kodwa i-cores edla amandla kunye nokungasebenzi kakuhle, kodwa ii-cores ezisebenza ngamandla kwi-chip enye.
Ngaphandle koko, nayo izibuko le-RISC-V livelele, okwathi ngeli xesha lokukhululwa, umsebenzi obalulekileyo wenziwe ngaphakathi ukuze ufumane i-dom0 ukuqala kwi-hardware ye-RISC-V, igxininise ekuqaliseni ukusebenza ukuze kuvunyelwe ulawulo lokuphazamiseka, kunye nolunye ujongano olufunekayo kwikhowudi yokuqalisa kwangaphambili.
Olunye utshintsho evelele kule nguqulo intsha:
- Yongezwe ukukwazi ukuqalisa kwizixhobo ze-Intel ngaphandle kweProgrammable Interval Timer (PIT).
- Kwiindwendwe ze-ARM, inkxaso yokuqala yezixhobo zokubala zokubeka iliso zokwenziwa komsebenzi iye yaphunyezwa.
- Ukonyuka kwenkxaso yehardware ngokuvumela iXen ukuba iqalise kwizixhobo ze-Intel ezingenaso isibali-xesha esicwangcisiweyo.
- Ukucocwa kwamacandelo elifa xa uyeka ukuqulunqa iQEMU Traditional okanye iPV-Grub ngokuzenzekelayo. Qaphela ukuba zombini iiprojekthi zidibanise inkxaso ye-Xen enyukayo ngoku, ke ukusebenzisa iifolokhwe ezikhethekileyo ze-Xen akusacetyiswa.
- Inkxaso yokuqala yeekhawuntari zokubeka iliso zokwenziwa kweendwendwe kwiArm.
- Uphuculo lwenkxaso kwiinkqubo ze-64-bit Arm ezingafaniyo ngokubeka iindima ze-CPU kuzo zonke ukuphucula inkxaso enkulu.LITTLE.
Gqibela ukuba unomdla wokwazi ngakumbi ngayo, unokubonisana iinkcukacha kwikhonkco elilandelayo. Ukukhutshwa kohlaziyo lwesebe le-Xen 4.16 kuya kuhlala kude kube ngumhla wesi-2 kuJuni ngo-2023 kunye nokukhutshwa kwezilungiso zobuthathaka kude kube ngumhla wesi-2 kuDisemba, ngo-2024.
