Virtio-fs is in RFC state, it could be OK as long as it doesn't have native gap for supporting live migration, and I will be glad to see it being listed in some roadmap.

Migration is always good to have at the QEMU level, so I'm sure we'll look into it more deeply. It's tricky when sharing local file systems because the destination host must have access to the same files in order for migration to be possible. One approach is to carefully copy the files during live migration. The file system daemon must also migrate its state (e.g. open files and handles). It's non-trivial but can be done with enough development effort. Stefan
