Azienda Microsoft ha presentato<\/a><\/noindex> per discutere nella mailing list degli sviluppatori del kernel Linux una serie di patch che consentono al hypervisor Hyper-V di lavorare con un ambiente root basato su Linux, con accesso diretto all'hardware e utilizzato per l'esecuzione di sistemi guest (simile a Dom0 in Xen). Fino ad ora, Hyper-V (Microsoft Hypervisor) supportava Linux solo in ambienti guest, ma l'hypervisor stesso era gestito da un ambiente basato su Windows. Ora, Microsoft intende creare un'intera stack di virtualizzazione con Linux e Hyper-V. <\/p>\n

L'organizzazione del lavoro dell'hypervisor nel kernel Linux e in Windows \u00e8 notevolmente diversa, quindi nell'implementazione di Hyper-V per Linux viene applicato un approccio diverso alla configurazione delle sottosistemi e all'organizzazione delle chiamate ipervirtuali. Il codice per il mapping delle interruzioni con l'uso di IOMMU \u00e8 stato riscritto in modo simile al codice di supporto di Xen in Linux (Xen e Hyper-V hanno un'architettura<\/a><\/noindex> simile<\/a><\/noindex> e si basano sull'utilizzo di un ambiente root\/Dom0 privilegiato per la gestione).<\/p>\n

Le patch sono una realizzazione minima necessaria per il funzionamento, proposta come prototipo iniziale per discussioni e critiche. Per la gestione dell'hypervisor, si propone il dispositivo \/dev\/mshv tramite il quale le applicazioni nello spazio utente possono creare e avviare macchine virtuali. \u00c8 inoltre proposto un porting dell'hypervisor ad alto livello Cloud Hypervisor<\/a><\/noindex>, consentendo di caricare macchine virtuali sopra Hyper-V invece di KVM. <\/p>\n

Nel 2018, il numero di sistemi guest con Linux nel servizio cloud Azure ha superato<\/a><\/noindex> gli ambienti basati su Windows, la cui quota \u00e8 in costante diminuzione, principalmente grazie alla crescente popolarit\u00e0 delle piattaforme devops e di Kubernetes, legate a Linux. L'uso di un unico stack basato su Linux potrebbe semplificare la manutenzione e migliorare le prestazioni dei server Hyper-V, che gestiscono sistemi guest con Linux.<\/p>\n
