I am a 2nd-year PhD student, in Department of Computer Science, the University of Hong Kong. My research interest is mainly about virtualization technologies for cloud computing, including but not limited to VM scheduling, I/O models, and guest OS design. I have been using/researching Xen since 2009 and have published several papers about Xen’s I/O performance in reputable conferences. I have the speaking experience in several international conferences.
