Explore the challenges and solutions for implementing dynamic configuration changes in virtual machines within the KubeVirt ecosystem in this DevConf.CZ 2023 conference talk. Delve into the complexities of device hotplugging, particularly for networking devices, in the context of Kubernetes orchestration and the libvirt/QEMU virtualization stack. Learn how speakers Andrea Bolognani and Edward Haas propose to address these challenges, aiming to provide KubeVirt users with a simplified, high-level interface for resource allocation. Gain insights into the critical feature of runtime configuration changes in VMs and understand the unique obstacles presented by the underlying platforms. While basic knowledge of KubeVirt and libvirt is beneficial, it is not mandatory for attending this 29-minute presentation.
