We give a multifaceted insight into what’s going on with virtio-fs, from the current state and future prospects of live migration support, where we have made considerable progress, over experimental areas, to a look at performance.
Some experimental areas are the support for non-vhost-user interfaces, such as /dev/fuse and vDPA/VDUSE, and to go beyond our simple passthrough driver, both via filesystem “transformation” functionality (e.g. UID/GID mapping) and by including native drivers such as network filesystem drivers.
As for virtio-fs’s performance, we’re going to have a look at both the interface, specifically multiqueue support, and virtiofsd’s internal architecture.
