Virtio-fs is getting widely used, especially for VMs that are running secure containers. To increase the reliability of the services relying on Virtio-fs in large production deployments, we extend Virtio-fs implementation to support high-availability features includes virtiofsd crash recovery, virtiofsd live-upgrade, and VM live-migration when using Virtio-fs. This talk will first introduce the use cases of Virtio-fs, and why Virtio-fs high-availability features are essential. Then, the talk will detail the designs and implementations of the features. Finally, the talk will state the current limitations and future development plans of these features.
