Although the Virtio block device is quite different from traditional Xen PV block device (vbd) from the toolstack's point of view: - as the frontend is virtio-blk which is not a Xenbus driver, nothing written to Xenstore are fetched by the frontend currently ("vdev" is not passed to the frontend). But this might need to be revised in future, so frontend data might be written to Xenstore in order to support hotplugging virtio devices or passing the backend domain id on arch where the device-tree is not available. - the ring-ref/event-channel are not used for the backend<->frontend communication, the proposed IPC for Virtio is IOREQ/DM it is still a "block device" and ought to be integrated in existing "disk" handling. So, re-use (and adapt) "disk" parsing/configuration logic to deal with Virtio devices as well. For the immediate purpose and an ability to extend that support for other use-cases in future (Qemu, virtio-pci, etc) perform the following actions: - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect that in the configuration - Introduce new disk "specification" and "transport" fields to struct libxl_device_disk. Both are written to the Xenstore. The transport field is only used for the specification "virtio" and it assumes only "mmio" value for now. - Introduce new "specification" option with "xen" communication protocol being default value. - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model An example of domain configuration for Virtio disk: disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio'] Nothing has changed for default Xen disk configuration. Please note, this patch is not enough for virtio-disk to work on Xen (Arm), as for every Virtio device (including disk) we need to allocate Virtio MMIO params (IRQ and memory region) and pass them to the backend, also update Guest device-tree. The subsequent patch will add these missing bits. For the current patch, the default "irq" and "base" are just written to the Xenstore. This is not an ideal splitting, but this way we avoid breaking the bisectability.

Although the Virtio block device is quite different from traditional Xen PV block device (vbd) from the toolstack's point of view: - as the frontend is virtio-blk which is not a Xenbus driver, nothing written to Xenstore are fetched by the frontend currently ("vdev" is not passed to the frontend). But this might need to be revised in future, so frontend data might be written to Xenstore in order to support hotplugging virtio devices or passing the backend domain id on arch where the device-tree is not available. - the ring-ref/event-channel are not used for the backend<->frontend communication, the proposed IPC for Virtio is IOREQ/DM it is still a "block device" and ought to be integrated in existing "disk" handling. So, re-use (and adapt) "disk" parsing/configuration logic to deal with Virtio devices as well. For the immediate purpose and an ability to extend that support for other use-cases in future (Qemu, virtio-pci, etc) perform the following actions: - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect that in the configuration - Introduce new disk "specification" and "transport" fields to struct libxl_device_disk. Both are written to the Xenstore. The transport field is only used for the specification "virtio" and it assumes only "mmio" value for now. - Introduce new "specification" option with "xen" communication protocol being default value. - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model An example of domain configuration for Virtio disk: disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio'] Nothing has changed for default Xen disk configuration. Please note, this patch is not enough for virtio-disk to work on Xen (Arm), as for every Virtio device (including disk) we need to allocate Virtio MMIO params (IRQ and memory region) and pass them to the backend, also update Guest device-tree. The subsequent patch will add these missing bits. For the current patch, the default "irq" and "base" are just written to the Xenstore. This is not an ideal splitting, but this way we avoid breaking the bisectability.
