Towards high-quality I/O virtualization
Yaozu Dong, Jinquan Dai, Zhiteng Huang, Haibing Guan, Kevin Tian, Yunhong Jiang · 2009
High-quality I/O virtualization (that is, complete device semantics, full-feature set, close-to-native performance and real-time response) is critical to both server and client virtualizations. Existing solutions for I/O virtualization (e.g., full device emulation, paravirtualization and direct I/O) cannot meet the requirements of high-quality I/O virtualization due to high overheads, lack of complete semantic or full-feature set support.
