KubeVirt on the Loose: Kubernetes-Powered VM Migrations That Defy Gravity - Ronny Issac

This session focuses on freeing workloads from traditional maintenance windows by utilizing KubeVirt, which dynamically relocates running Virtual Machines (VMs) between Kubernetes nodes. The speaker explains how KubeVirt enables continuous application availability during upgrades, scaling, or node failures through orchestrated memory transfers and status checks. Key techniques such as "pre-copy" and "stop-and-copy" methods are discussed, alongside solutions for managing high dirty rates, including "auto-converge." Attendees will learn best practices for migration timeouts and traffic isolation, and explore real-world scenarios involving node maintenance and heavy VM management. The speaker, Ronny Issac, has extensive experience in infrastructure roles at major companies and currently leads engineering at Kubermatic, focusing on Kubernetes and cloud-native solutions.
