How We Tackle KubeVirt’s Growth and Scalability
Talkat KubeCon + CloudNativeCon Europe 2025 · on Friday, 2025-04-04· at 11:45· Level 3 | ICC Capital Suite 7-9·
summary
KubeVirt adopts a lightweight virtualization enhancement process to spread design review across SIGs and produce a roadmap, automates daily scale benchmarking with phase‑transition metrics, and integrates Kwok to simulate nodes so CI creates 1,000 VMIs in seconds on a tiny cluster, cutting infra cost. CI stores metrics in S3, plots daily runs and weekly aggregates to catch regressions, and uses Quark/Kwok CRs plus service‑account impersonation to let fake VMIs pass webhook validation.
