• 論文抄録 / 内容記述: Recent virtualization technologies combine para-virtualization and hardware-assisted virtualization techniques as so-called hybrid-virtualization. Para-virtualization and hardware-assisted virtualization have performance issues in different aspects respectively but combined use of both sometimes compensates for the issues of each thus potentially gains better performance. Although KVM acquires reasonable I/O performance through this hybrid-virtualization approach we believe its I/O performance has room for improvement. To this end we investigate how KVM handles network I/O report its recent improvement with a para-virtualized network driver and finally describe a perspective toward further improvement based on the investigation.
