Tso tawm ntawm Xen 4.14 hypervisor

Tom qab yim lub hlis ntawm kev loj hlob luam tawm pub dawb hypervisor tso tawm Ib 4.14. Cov tuam txhab xws li Alibaba, Amazon, AMD, Arm, Bitdefender, Citrix, EPAM Systems, Huawei thiab Intel tau koom nrog hauv kev tsim tawm tshiab. Kev tso tawm cov kev hloov tshiab rau Xen 4.14 ceg yuav kav mus txog Lub Ib Hlis 24, 2022, thiab tshaj tawm cov kev hloov kho tsis zoo kom txog thaum Lub Xya Hli 24, 2023.

Ntsiab hloov hauv Xen 4.14:

• Ntxiv kev txhawb nqa rau cov khoom siv tshiab Linux stubdomain, uas tso cai rau koj los teeb tsa kev ua tiav raws li tus neeg siv tsis muaj cai sib cais, cais cov khoom sib cais rau cov khoom siv emulation los ntawm Dom0. Yav dhau los, nyob rau hauv stubdomain hom, tsuas yog cov "qemu-ib txwm" cov qauv siv tau, uas txwv cov khoom siv emulated. Tus qauv tshiab Linux cov ntsiab lus tau tsim los ntawm QUBES OS qhov project thiab txhawb kev siv cov tsav tsheb emulation los ntawm cov kev tshaj tawm tshiab tshaj plaws ntawm QEMU, nrog rau cov qhua muaj peev xwm muaj peev xwm muaj nyob hauv QEMU.
• Rau cov tshuab nrog Intel EPT kev txhawb nqa, kev txhawb nqa rau kev tsim cov ceg tawv (forks) ntawm cov tshuab virtual yog siv rau kev soj ntsuam ceev, piv txwv li, rau kev soj ntsuam malware lossis kev sim fuzzing. Cov diav rawg no siv lub cim xeeb sib koom thiab tsis txhob clone tus qauv ntaus ntawv.
• Lub tshuab nyob thaj tau ntxiv rau kev txuas mus rau hypervisor los ua ke tus cim thiab coj mus rau hauv tus account qhov kev txiav txim uas siv thaj ua rau thaj kom tiv thaiv thaj chaw los ntawm kev siv rau kev sib dhos tsis raug lossis tsis ncaj ncees lawm.
• Ntxiv kev txhawb nqa rau CET (Intel Control-flow Enforcement Technology) txuas ntxiv los tiv thaiv kev siv dag zog tsim los siv cov txheej txheem rov qab los qhia txog kev ua haujlwm (ROP, Rov Qab-Oriented Programming) cov txheej txheem.
• Ntxiv CONFIG_PV32 teeb tsa kom lov tes taw kev txhawb nqa hypervisor rau 32-ntsis paravirtualized (PV) qhua thaum tswj kev txhawb nqa rau 64-ntsis sawv daws yuav.
• Ntxiv kev txhawb nqa rau Hypervisor FS, pseudo-FS nyob rau hauv sysfs style rau kev nkag mus rau cov ntaub ntawv sab hauv thiab kev teeb tsa ntawm hypervisor, uas tsis tas yuav parsing cav lossis sau hypercalls.
• Nws muaj peev xwm khiav Xen raws li tus qhua system khiav Hyper-V hypervisor siv hauv Microsoft Azure huab platform. Khiav Xen hauv Hyper-V tso cai rau koj siv cov kev paub virtualization pawg hauv Azure huab ib puag ncig thiab ua rau nws tuaj yeem txav cov tshuab virtual ntawm cov huab sib txawv.
• Ntxiv qhov muaj peev xwm los tsim kom muaj tus qhua tuaj yeem ID (yav dhau los IDs tau tsim ua ntu zus). Tam sim no tus lej tseem tuaj yeem txuas ntxiv nyob nruab nrab ntawm VM lub xeev txuag, rov qab los, thiab ua haujlwm tsiv teb tsaws chaw.
• Tsis siv neeg tsim kev khi rau cov lus Go raws li cov qauv libxl tau muab.
• Rau Windows 7, 8.x thiab 10, kev txhawb nqa rau KDD tau ntxiv, qhov khoom siv rau kev cuam tshuam nrog WinDbg debugger (Windows Debugger), uas tso cai rau koj los daws qhov teeb meem Windows ib puag ncig yam tsis tau ua kom debugging hauv cov qhua OS.
• Ntxiv kev txhawb nqa rau tag nrho Raspberry Pi 4 pawg thawj coj sib txawv uas xa nrog 4GB thiab 8GB RAM.
• Ntxiv kev txhawb nqa rau AMD EPYC processors codenamed "Milan".
• Txhim kho kev ua tau zoo rau nested virtualization, uas khiav Xen hauv Xen- lossis Viridian-raws li cov qhua.
• Hauv hom emulation, kev txhawb nqa rau AVX512_BF16 cov lus qhia raug siv.
• Lub rooj sib txoos hypervisor tau hloov mus siv Kbuild.
