Xen Project Contributor Spotlight: Kevin Tian

The Xen Project is comprised of a diverse set of member companies and contributors that are committed to the growth and success of the Xen Project Hypervisor. The Xen Project Hypervisor is a staple technology for server and cloud vendors, and is gaining traction in the embedded, security and automotive space. This blog series highlights the companies contributing to the changes and growth being made to the Xen Project and how the Xen Project technology bolsters their business.

Title: Principal Engineer of Open Source Technology Center
Company: Intel

When did you join the Xen Project and why/how is your organizations involved?
My journey with Xen Project has been ~13 years now (since 2005), with a focus on hardware-assisted virtualization using Intel® Virtualization Technology (Intel® VT). I’m acting as the maintainer for VT-x/VT-d sub-system in the Xen Project community. The Xen Project is the first open source virtualization project embracing Intel® VT and is a leading community in demonstrating new hardware virtualization features.

How does your involvement benefit your company?
Working with open source communities can definitely bring great value to the whole ecosystem around new technologies, which Intel debuts every year. For example, being the pioneer on Intel® VT, the success in the Xen Project accelerated the market transition from software-based virtualization (binary translation, para-virtualization, etc.) to hardware-assisted virtualization (HVM, PVH, etc.). Hardware-assisted virtualization helps with reduced maintenance overhead, full guest OS compatibility, and better performance.

How does the Xen Project’s technology help your business?
The ecosystem built around the Xen Project is definitely helpful in generating demand of Intel servers (with Intel® VT).

What are some of the major changes you see with virtualization and the transition to cloud native computing?
While virtualization technology has become the fundamental building block in the Cloud, there is still a major gap regarding I/O capabilities when comparing virtualized environment to bare metal. Although network and storage virtualization has been in place for years, efficient virtualization and sharing of new booming accelerators (GPU, NVMe, FPGA, QAT, etc.) are still not widely available. The ceiling of what cloud-native computing can achieve could be severely limited, if disconnected from powerful accelerators existing in the physical server.

What advice would you give someone considering joining the Xen Project?
The Xen Project is possibly one of the most successful open source virtualization projects in the world. The mature community and rich features accumulated in the decade plus the project has been in existence has provided a strong foundation to save you time – either in developing a value-add business or exploiting new virtualization research.

What excites you most about the future of Xen?
I’m excited by the fact that the Xen Project keeps embracing new innovations, e.g. PVH, XenGT, etc., and penetrating new markets.

The Xen Project is participating in 2018 Summer round of Outreachy

This is a quick reminder that the Xen Project is again participating in Outreachy (May 2018 to August 2018 Round). Please check the Outreachy application page for more information.

Outreach Program for Women has been helping women (cis and trans), trans men, and genderqueer people get involved in free and open source software worldwide. Note that the program has been extended and is now also open to people from other groups underrepresented in FOSS: specifically the program is open to residents and nationals of the United States of any gender who are Black/African American, Hispanic/Latin, American Indian, Alaska Native, Native Hawaiian, or Pacific Islander. Information on Eligibility and the application process can be found here.

Meet us at FOSDEM 2018

As in the past, the Xen Project will have a booth at Europe’s biggest open source conference FOSDEM (taking place February 3rd and 4th in Brussels, Belgium).

Where?

During FOSDEM community volunteers will man our booth, which is located in bulding K (level 1, group C).

Meet the Team!

You will have the opportunity to speak to some of our developers: Anthony Perard (Maintainer of various components and qemu developer, Citrix), Daniel Kiper (Xen and Grub developer, Oracle) – Daniel will be mostly on the Grub booth, Ian Jackson (Committer and maintainer of various components, Citrix), Lars Kurth (Community Manager, Citrix), Roger Pau Monné (Maintainer of various components most recently PVH, Citrix), Simon Künzer (Project Lead of Unikraft, NEC) and Wim ten Have (Xen and libvirt developer, Oracle). We also have Julien Fontanet (CTO, Vates) and Olivier Lambert (CEO, Vates) from Xen Orchestra at our booth!

We also have a few talks in the Virtualisation Devroom.
