Gli ingegneri di Google hanno pubblicato per la discussione degli sviluppatori del kernel Linux un insieme di patch che implementano il sistema Live Update Orchestrator (LUO), progettato per aggiornare il kernel in modalit\u00e0 Live. A differenza di meccanismi come livepatch, Ksplice, kpatch e kGraft, il nuovo sistema non si limita alla possibilit\u00e0 di applicare singole correzioni a un kernel Linux in esecuzione, ma consente di riavviare e aggiornare completamente il kernel senza interrompere il funzionamento degli specifici dispositivi. Il progetto si basa su un insieme di patch KHO (Kexec HandOver) per il meccanismo kexec, utilizzato per caricare un nuovo kernel da un kernel Linux gi\u00e0 avviato senza un riavvio fisico. <\/p>\n

Come principale area di utilizzo di LUO vengono menzionati gli ambienti cloud, nei quali sar\u00e0 possibile aggiornare l'iperstazionale KVM senza interrompere il funzionamento delle macchine virtuali in esecuzione. di macchine virtuali<\/a>In particolare, sar\u00e0 possibile sospendere macchine virtuali<\/a> temporaneamente il riavvio del kernel con l'iperstazionale, mantenendo attivi tutti i dispositivi collegati alle macchine virtuali. <\/p>\n

Per realizzare questa possibilit\u00e0, LUO offre funzionalit\u00e0 per il salvataggio dello stato dei dispositivi prima del passaggio al nuovo kernel e il ripristino dello stato immediatamente dopo l'attivazione del nuovo kernel in modo che le operazioni continue del sistema e delle applicazioni nello spazio utente con i dispositivi non vengano interrotte. Durante il riavvio del kernel, \u00e8 anche garantita l'integrit\u00e0 delle operazioni eseguite con DMA e l'attivit\u00e0 associata al trattamento delle interruzioni. <\/p>\n

Per coordinare il salvataggio dello stato e il passaggio al nuovo kernel, LUO fornisce un'API che consente ad altri sottosistemi del kernel di collegare gestori per monitorare e partecipare al processo di riavvio Live. Tra i sottosistemi che possono integrarsi con LUO ci sono l'iperstazionale KVM, iommu, sistema delle interruzioni e driver. Per il trasferimento dello stato della memoria dal vecchio kernel al nuovo \u00e8 coinvolto KHO (Kexec HandOver). La gestione avviene tramite file sysfs \u00ab\/sys\/kernel\/liveupdate\/{state, prepare, finish}\u00bb.
