Xen 4.14 inouya nerutsigiro rwe stubdomain Linux, Hypervisor FS uye nezvimwe

Mushure memwedzi misere yekuvandudza yakazozivikanwa kuvhurwa kweshanduro nyowani ye xen 4.14, iyo mukusimudzira yakatora chikamu mumakambani akaita seAlibaba, Amazon, AMD, Arm, Bitdefender, Citrix, EPAM Systems, Huawei neIntel.

Kune avo vasina kujaira Xen, iwe unofanirwa kuziva izvo yakavhurwa sosi chaiyo muchina wekutarisa yakagadzirwa neYunivhesiti yeCambridge. Dhizaini yekugadzira ndeyekukwanisa kumhanyisa zviitiko zvinoshanda zvehurongwa nenzira inoshanda zvizere pane imwechete komputa.

xen inopa yakazvimiririra yekuzvimiririra, kudzora zviwanikwa, mhando yevhisi yebasa uye inopisa inopisa muchina kutama. Masisitimu anoshanda anogona kushandurwa zvakajeka kuti amhanye Xen (uku uchichengetedza kuenderana nemashandisirwo emushandisi).

Izvi zvinogonesa Xen kuzadzikisa kuita kwepamusoro-kuita. pasina yakakosha Hardware rutsigiro. Intel yaita mipiro yakati wandei kuXen iyo yawedzera rutsigiro kune yayo VT-X Vanderpool ekuwedzera ekuwedzera.

Iyi tekinoroji inobvumidza isina kugadziridzwa masisitimu anoshanda kuti aite seanogadzira mukati memachina chaiwo Xen, chero bedzi sevha yepanyama inotsigira iyo Intel VT kana AMD Pacifica yekuwedzera.

Xen 1.14 Zvitsva Zvitsva Zvitsva

Muchikamu chitsva ichi chimwe chezvinhu zvikuru zvitsva ndeye rutsigiro rutsva rweiyo nyowani stubdomain Linux mudziyo modhique inobvumira kuronga kuuraya pasi pemumwe mushandisi asina rombo, kupatsanura izvo zvinhu zveiyo Dom0 chishandiso.

Pakutanga, iyo chete "qemu-yechinyakare" modhi yedhijidhi inogona kushandiswa mune stubdomain mode, iyo inogumira huwandu hwesimbi inoteedzerwa. Iyo nyowani modhikana kubva kuLinux stubomains yakagadzirwa neiyo QUBES OS chirongwa uye inotsigira kushandiswa kweanoteedzera madhiraivha kubva kuazvino vhezheni yeQEMU, pamwe nehukama hwevaenzi hunowanikwa muQEMU.

Kune masystem ane Intel EPT rutsigiro, rutsigiro rwekusika Chiedza chakareruka chemuchina lightweights ekukurumidza kuongorora, semuenzaniso, yekuongorora malware kana kuyedza fuzzing. Mapazi akaita seichi anoshandisa ndangariro dzakagovaniswa uye haaumbanise modhi yedhijidhi.

Iyo yekurarama chigamba sisitimu yakawedzera zvinongedzo kune iyo hypervisor musangano ids uye yakatarisira kurongeka kwekutsemura kudzivirira kuwanda kwemapatch emachechi asiri iwo kana nenzira isiriyo.

Imwe shanduko yakakosha iri mu rutsigiro rwekuwedzera kweCET (Intel Control-flow Enforcing Technology) kudzivirira kubva pakuitwa kwekushandisa kwakagadzirwa uchishandisa Kudzoka-Yakatemerwa Programming (ROP) matekiniki.

Kugadziriswa kwakawedzerwa CONFIG_PV32 kudzima hypervisor rutsigiro yevashanyi vepa para-optimized (PV) 32-bit uchichengetedza 64-bit rutsigiro.

Wakawedzera rutsigiro rweHypervisor FS, sysf-maitiro pseudo-FSs yeakagadziriswa kuwana kune yemukati data uye marongero ye hypervisor iyo isingade marekodhi ekunyora kana kunyora hypercalls.

Uyewo akawedzera kugona kumhanyisa Xen semuyenzi ari kumhanyisa Hyper-V hypervisor inoshandiswa papuratifomu yegore yeMicrosoft Azure. Kumhanya Xen mukati meHyper-V inokutendera iwe kushandisa yakajairika virtualization stack munzvimbo yeAzure yegore uye inoita kuti zvikwanise kufambisa chaiwo michina pakati peakasiyana makore masisitimu.

Yeimwe shanduko:

  • Wakawedzera kugona kuburitsa yakasarudzika system yevaenzi chitupa (zvirevo zviri pamusoro zvakagadzirwa zvakateerana).
  • MaID anogona ikozvino kuenderera pakati pekuchengetedza, kudzoreredza, uye VM mamiriro ekufambisa.
  • Otomatiki chizvarwa cheGo zvinongedzo zvinoenderana ne libxl zvimiro.
  • ZveWindows 7, 8.x uye 10, rutsigiro rwakawedzerwa KDD, chinoshandiswa kudyidzana neWinDbg (Windows Debugger) debugger, iyo inobvumidza iwe kugadzirisa mamiriro eWindows pasina kugonesa kugadzirisa mune yevaenzi sisitimu.
  • Wakawedzera rutsigiro rweese Raspberry Pi 4 bhodhi akasiyana anouya ne4GB uye 8GB ye RAM.
  • Wakawedzera rutsigiro rwe AMD EPYC processor yakadomwa zita rekuti "Milan".
  • Nested virtualization performance uko Xen inomhanya mukati meXen- kana yeViridian-based vashanyi yakagadziridzwa.
  • Mune emulation modhi, rutsigiro rweAVX512_BF16 mirairo inoitwa.

Kana iwe uchida kuziva zvakawanda nezvazvo, unogona kubvunza ruzivo mune inotevera chinongedzo.

Kuburitswa kweyekuvandudzwa kwebazi reXen 4.14 kunogara kusvika muna Ndira 24, 2022, uye kuburitswa kwekugadziriswa kwekugadziriswa kusvika muna Chikunguru 24, 2023.


Izvo zviri muchinyorwa zvinoomerera pamisimboti yedu ye tsika dzekunyora. Kuti utaure chikanganiso tinya pano.
