Interview: Yaozu (Eddie) Dong, Open Source Virtualization Expert

By Dawn M. Foster (84 posts) on November 5, 2009 at 8:00 am

Yaozu (Eddie) Dong is a technical lead in the Open Source Technology Center in Shanghai, PRC. He joined Intel in 1998 and had been involved in various embedded system projects from PalmOS to Windows CE to Linux, and several virtualization projects. He received his Bachelors and Masters degrees in Engineering from Shanghai Jiao Tong University, PRC.

Dawn: What do you like about working in Intel's Open Source Technology Center?

Eddie: Intel's Open Source Technology Center is a great place where I learned, grew up and contributed. The team here in China is young, open and skillful, and we all are in a very good atmosphere to help each other and work as a team. Each individual contribution is small, but we are proud of the whole team effort. That is the sole reason we received an Intel Achievement Award in 2006.

Dawn: How are you involved in performance tuning work for open source virtualization projects?

Eddie: I started my virtualization life in early 2004, and started working on open source virtualization projects, i.e. Xen, at the end of year. Performance is critical to the success of open source virtualization projects, but it was not that good at that time. I started the work with help from the team, accumulated all the expertise necessary and was able to improve it dramatically both in Xen and KVM.

Dawn: Can you tell us more about your efforts with SR-IOV Networking in the Xen project?

Eddie: SR-IOV, as part of Intel Virtualization Technology for Connectivity, is a significant product to improve I/O virtualization performance. It takes the advantage of Intel Virtualization Technology for directed I/O, i.e. VT-d, to reduce the intervention of hypervisor in I/O sharing. As a team, we implemented the SR-IOV support for open source virtualization and tuned the performance to achieve close to native performance.

Dawn: What do you do for fun when you aren't working at Intel?

Eddie: I like to spend time with my kid, playing chess or having fun together.
