Cloud Native Theater | KubeVirt Summit: KubeVirt on GB200: Vi... Fan Zhang, Kevin Klues & Alay Patel

This talk explores the implementation of KubeVirt on the GB200, a rack-scale supercomputer that redefines virtualization compared to traditional PCIe-based servers. The speakers, Fan Zhang, Kevin Klues, and Alay Patel from NVIDIA, discuss how the GB200 architecture couples CPU and GPU through a cache-coherent interconnect, leading to significant changes in the VFIO/QEMU/Kubernetes stack. Attendees learn about the necessary VFIO and kernel requirements, QEMU/libvirt specifications, andTopology Manager requirements for Device Plugins or DRA usage, as well as the orchestration of Compute Domains and guest topology pass-through. By the end of the session, participants gain a comprehensive understanding of integrating KubeVirt with GB200-class racks, along with a practical validation checklist.
