If the Live migration of virtio-fs is still at the early discussion stage AFAICT. It might take time before we have something working. But in the meantime, it seems abusive to block migration if we have a guarantee that the device isn't servicing requests. FWIW virtio-9p only blocks migration when the shared directory is mounted on the guest. > shared directory is from a distributed file system like Ceph, would it > be easier than the general case to be implemented? > > Thanks, > Xiongzi > > > > _______________________________________________ > Virtio-fs mailing list > Virtio-fs@redhat.com > https://listman.redhat.com/mailman/listinfo/virtio-fs >
