UNICORE members Felipe Huici, from NEC, and Costin Lupu, from University Politehnica of Bucharest, were present on May 25th at the Xen Project Developer & Design Summit 2021.
The Xen Project Developer and Design Summit brings together the Xen Project’s community of developers and power users for their annual developer conference. The conference is about sharing ideas and the latest developments, sharing experience, planning, collaboration and above all to have fun and to meet the community that defines the Xen Project. This year’s conference took part on May 25 – 28, 2021.
Felipe Huici presented the paper “Unikraft Weather Report” at 17:30, on May 25th. He gave an update of all the activities that have taken place, including a major effort to transparently support off-the-shelf applications via binary compatibility and musl support; ongoing integration efforts with orchestration frameworks such as Kubernetes; significant improvements to performance; important performance improvements to Unikraft’s Xen netfront driver; and ongoing efforts that allow Unikraft to comparmentalize each of its libraries and thus build security-hardened images.
Costin Lupu presented the paper “Cloning Unikernels on Xen” at 18:00, on May 25th. His presentation proposed a solution based on Xen by adding cloning support for unikernels. He tried to clarify the semantics of the fork call for a unikernel and how it can be supported on a Xen environment by reusing as much as possible the available functionality in both hypervisor and toolstack.
