Xen ndeye hypervisor inopa yakachengeteka yekuzviparadzanisa nevamwe, kudzora zviwanikwa, mhando yebasa garandi, uye chaiwo muchina wekufamba.
Mushure memwedzi ye11 yekuvandudzwa, uyeIyo Xen purojekiti yakazivisa kutangwa kweiyo vhezheni itsva de "Xen 4.18", iyo inosvika yakatakura zvinhu zvakawanda uye kuvandudzwa, pamwe nekumwe kufambira mberi kwakanangana nepamusoro pekushanda komputa (HPC) zvikumbiro, kudzidza muchina (ML) uye zvakasiyana-siyana zvekuchengetedza nekuvandudzwa kwemaitiro.
Kune avo vasingazive nezve Xen Project, iwe unofanirwa kuziva kuti iyi yakavhurika sosi hypervisor inotsigira x86, x86_64, IA64, PowerPC uye mamwe maCPU architecture.
"Kuburitswa uku kunopa hutsva hwepamusoro uye hwekuchengetedza bhizinesi maficha, asi zvakare inogadzirira zvivakwa zveHPC neAI / ML zvikumbiro, izvo zvinoda huwandu hukuru hwekugadziriswa kwedata," akadaro Kelly Choi, maneja wenharaunda yeXen Project. "Tinoda kutenda vatungamiriri veindasitiri nevagadzirisi vakabatsira mukuvhurwa."
Xen 4.18 Zvitsva Zvitsva Zvitsva
Muiyi vhezheni nyowani yeXen 4.18 inoratidzwa, inosimbiswa kuti yeArm architecture, Scalable Vector Extension inounzwa (EVS) mune preview form iyo inovimbisa kugona kwakawedzerwa kweArm system, pamwe neyekuyeuka subsystem muXen paArm64 yaona kuvandudzwa, zvichiita kuti ienderane neArm architecture.
Uyewo yakawedzera Arm firmware framework rutsigiro rweArm Profile A (FF-A) uye yakawedzera kuyedza kugona kuwedzera nekubvisa node zvine simba mumuti weXen mudziyo uchishandisa .dtbo mafaera.
Nezve kuvandudzwa kwe x86, pane masisitimu ane Intel processors, Xen 4.18 inowedzera rutsigiro rwayo ne iyo MSR_ARCH_CAPS parameter, yava kuonekwa nevaenzi uye inogona kugadzirwa kuburikidza neiyo virtual muchina kumisikidza faira. Pama processor akaburitswa muna 2019 uye gare gare, iyo MSR_ARCH_CAPS paramende inokutendera iwe kuti uone kuti ndezvipi zvigadziriso zvehardware zvakaiswa mukusagadzikana kwekufungidzira.
Pamusoro peizvi, yakashandiswa tsigiro yekumanikidzwa kuurayiwa kwehurongwa hwekuita muDOITM, iyo inovimbisa nguva dzose yekuita nguva yemirairo, pasinei nedheta yakagadziriswa mumirairo iyi.
Kune rimwe divi, mune iyi vhezheni itsva yeXen 4.18 tinogona kuwana izvozvoeCPUID_USER_DIS (CPUID Faulting) yekuwedzera yakaiswa yakaitwa muchizvarwa chechina che AMD EPYC processors. Iyi yekuwedzera inobvumidza iwe kutarisa kugona kuona CPUID data kubva kune paravirtualized muenzi system.
Uyezve, yakasumwa tsigiro yezviwedzerwa zvazvino pane Intel-based processors Iyo Sapphire Rapids microarchitecture:
- Kune masisitimu evaenzi muHVM nePVH modhi, tsigiro yePKS (Protection Key Supervisor) meshini yakabatanidzwa, iyo inowedzera ndangariro kuchengetedza peji.
- Iyo VM-Notify michina yakaitwa kudzivirira kuvharika kwechimbichimbi kweiyo system yese kana paine matambudziko ane microarchitectural locks.
Yeimwe shanduko izvo zvinomira pachena:
- Kuitwa kwekutanga kwezviteshi zveRISC-V uye Power architectures zvakabatanidzwa.
- Nzvimbo dzakatarwa dzakaitwa kuyedza iyo RISC-V uye Power ports mukati meGitLab CI inoenderera mberi yekubatanidza system.
- Kudzivirira kuvharika kwebhazi zvichikonzerwa nekushandisa zvisirizvo kwemirairo yeatomu muhurongwa hwevaenzi, dziviriro yakaitwa nekugonesa chiyero chechiyero.
- Yakawedzera cpufreq mutyairi anoshandisa iyo HWP (Hardware P-States) nzira yekudzora mashandisiro emagetsi uye kuwanda kweIntel processors.
- Ma hypercalls maviri matsva akawedzerwa kuti amise kusungirirwa kwevCPU mashandiro ehurumende uye nzvimbo dzenguva pfupi kune kero dzepanyama panzvimbo peiyo chaiyo.
- Tsigiro yekusimbisa sisitimu-yakafara mashandiro mune data operand-yakasununguka nguva yekumisikidza
- MuRISC-V, kumwe kugadziridza uye kuvandudzwa kwakaitwa kune iripo kodhi. BUG/ WARN macros, printk uye decode_cause () mabasa enguva pfupi akaunzwa kudhinda chikonzero cheriva. Mukuburitswa kuri kuuya, mepu yekuzivikanwa, yakazara Xen kuunganidzwa, uye kubata musungo kuchaunzwa.
Chekupedzisira, zvakakosha kuti titaure kuti kuvandudzwa kweiyi vhezheni yeXen 4.18 ichawedzerwa kusvika Chivabvu 16, 2025, uye kuburitswa kwehudziviriro kugadzirisa kusvika Mbudzi 16, 2026.
Kana iwe uchida kudzidza zvakawanda nezve, unogona kubvunza ruzivo mune inotevera chinongedzo.
