Gli sviluppatori di XCP-ng, che stanno portando avanti un'alternativa libera e gratuita alla piattaforma proprietaria di gestione dell'infrastruttura cloud XenServer (Citrix Hypervisor), hanno annunciato il loro ingresso nel progetto Xen, la cui sviluppo \u00e8 condotto sotto l'egida della Linux Foundation. L'ingresso nel progetto Xen permetter\u00e0 di considerare XCP-ng come una distribuzione standard per il deployment di infrastrutture di macchine virtuali basate sul hypervisor Xen e su XAPI.<\/p>\n

L'unione con il progetto Xen consentir\u00e0 a XCP-ng, come distribuzione per gli utenti finali, di diventare un collegamento tra utenti e sviluppatori e di garantire agli utenti di XCP-ng che il progetto in futuro continuer\u00e0 a seguire i principi originariamente stabiliti (non si trasformer\u00e0 in un prodotto commerciale limitato, come accaduto con XenServer). L'unione non avr\u00e0 un impatto significativo sui processi di sviluppo utilizzati in XCP-ng.<\/p>\n

\u00c8 stato contemporaneamente proposto per il testing il rilascio beta di XCP-ng 8.1, che riproduce le funzionalit\u00e0 di Citrix Hypervisor 8.1 (precedentemente noto come XenServer). \u00c8 supportato l'aggiornamento da XenServer a XCP-ng, garantendo la piena compatibilit\u00e0 con Xen Orchestra e la possibilit\u00e0 di migrazione di macchine virtuali<\/a> da XenServer a XCP-ng e viceversa. \u00c8 stata preparata un'immagine di installazione da 530 MB per il download.<\/p>\n

Le immagini di installazione della nuova versione sono costruite su una base di pacchetti CentOS 7.5 utilizzando il kernel Linux 4.19 e l'iperbvisor Xen 4.13. Il cambiamento pi\u00f9 notevole in XCP-ng 8.1 \u00e8 stata la stabilizzazione del supporto per l'avvio dei sistemi guest in modalit\u00e0 UEFI (il supporto per il Secure Boot non \u00e8 stato trasferito, poich\u00e9 legato a codice proprietario). Inoltre, sono state migliorate le prestazioni di importazione ed esportazione delle macchine virtuali
\nin formato XVA, aumentate le prestazioni dello storage, aggiunti nuovi driver di input\/output per Windows, introdotto il supporto per i chip AMD EPYC 7xx2(P), sostituito ntpd con chrony, dichiarato obsoleto il supporto per i sistemi guest in modalit\u00e0 PV, e nei nuovi storage locali ora viene utilizzato di default il filesystem Ext4; il modulo sperimentale per ZFS \u00e8 stato aggiornato alla versione 0.8.2.<\/p>\n

Ricordiamo che Citrix Hypervisor (XenServer) e XCP-NG consentono un rapido deployment di sistemi di virtualizzazione server<\/a> e workstation, offrendo strumenti per la gestione centralizzata di un numero illimitato di server e macchine virtuali. Tra le caratteristiche del sistema: la possibilit\u00e0 di unire pi\u00f9 server in un pool (cluster), strumenti per garantire alta disponibilit\u00e0 (High Availability), supporto per snapshot, condivisione delle risorse tramite la tecnologia XenMotion. \u00c8 supportata la migrazione live delle macchine virtuali tra gli host del cluster e tra diversi cluster\/o singoli host (senza storage condiviso), cos\u00ec come la migrazione live dei dischi VM tra gli storage. La piattaforma pu\u00f2 operare con un elevato numero di sistemi di archiviazione e presenta un'interfaccia semplice e intuitiva per l'installazione e l'amministrazione.<\/p>\n
