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 (the vdev is not passed to the frontend) - 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_OTHER) and reflect that in the configuration - Introduce new disk protocol field to libxl_device_disk struct (with LIBXL_DISK_PROTOCOL_XEN and LIBXL_DISK_PROTOCOL_VIRTIO_MMIO types) and reflect that in the configuration (new "protocol" option with "xen" 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=other, protocol=virtio-mmio'] 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.

In order to deal with multiple Virtio devices, reserve corresponding ranges. For now, we reserve 1MB for memory regions and 10 SPIs. As these helpers should be used for every Virtio device attached to the Guest, call them for Virtio disk(s). Please note, with statically allocated Virtio IRQs there is a risk of a clash with a physical IRQs of passthrough devices. For the first version, it's fine, but we should consider allocating the Virtio IRQs automatically. Thankfully, we know in advance which IRQs will be used for passthrough to be able to choose non-clashed ones.
