Open Challenges for a Production-ready Cloud Environment on top of RISC-V hardware

As part of the Vitamin-V European project, we have built a prototype of a RISC-V cluster managed by OpenStack, with the goal of realizing a functional RISC-V cloud ecosystem. In this poster we explain the hardware and software challenges encountered while porting some elements of OpenStack. We also discuss the current performance gaps that challenge a performance-ready cloud environment over such new ISA, an essential element to fulfill in order to achieve european technological sovereignty.
