From: "Dr. David Alan Gilbert" <dgilb...@redhat.com> Hi, This pair of patches adds the core of the virtio-fs support to qemu; it's marked experimental since the kernel patch and spec changes aren't in yet; but they're bubbling along.
While the spec change is still in progress; the ID number is already reserved. A future set of patches will add the optional DAX mapping support. The actual qemu change is pretty minimal, since it's really only a virtio device with some queues.
