Google'i insenerid on v\u00e4lja andnud Linuxi tuumaloo arendajate aruteluks komplekti pat\u0161osid, mis rakendavad elavdamise t\u00e4itmise korraldaja (LUO) alams\u00fcsteemi, mis on m\u00f5eldud tuuma uuendamiseks reaalajas. Erinevalt sellistest mehhanismidest nagu livepatch, Ksplice, kpatch ja kGraft, ei piira uus s\u00fcsteem ainult v\u00f5imalust rakendada eraldi parandusi t\u00f6\u00f6tavale Linuxi tuumale, vaid v\u00f5imaldab t\u00e4ielikku taask\u00e4ivitamist ja tuuma uuendamist ilma, et see katkestaks \u00fcksikute seadmete t\u00f6\u00f6d. Projekt p\u00f5hineb KHO (Kexec HandOver) pat\u0161oide komplektil, mis rakendatakse kexec mehhanismi kaudu, et laadida uus tuum juba t\u00f6\u00f6tavast Linuxi tuumast ilma f\u00fc\u00fcsilise taask\u00e4ivitamiseta. <\/p>\n
Peamisteks kasutusvaldkondadeks on LUO nimetanud pilvekeskkonnad, kus on v\u00f5imalik uuendada KVM-i h\u00fcperviisorit ilma t\u00f6\u00f6tavate rakenduste katkestamiseta. virtuaalmasinate<\/a>Eelk\u00f5ige on v\u00f5imalik peatada virtuaalmasinaid<\/a> tuuma ja h\u00fcperviisori taask\u00e4ivitamise ajaks, hoides samal ajal k\u00f5ik virtuaalmasinatele kinnitatud seadmed t\u00f6\u00f6valmis. <\/p>\n Selle v\u00f5imaluse elluviimiseks annab LUO v\u00f5imalused seadmete oleku salvestamiseks enne \u00fcleminekut uuele tuumale ja selle oleku taastamiseks kohe p\u00e4rast uue tuuma rakendamist nii, et s\u00fcsteemi ja kasutajaavalduste pidevad toimingud seadmete kasutamisel ei oleks h\u00e4iritud. Tuuma taask\u00e4ivitamise protsessis tagatakse ka t\u00e4itmise katkestamiste t\u00f6\u00f6deldud operatsioonide pidevus ja aktiivsus. <\/p>\n \u0414\u043b\u044f
