There's are some other limitations to the number of virtio block devices. For instances... > sprintf(vblk->disk->disk_name, "vd%c", virtblk_index++); This gets bogus after 64 disks. We also have a hard limit for virtio-pci based on the number of PCI slots available. One thing I was considering was whether we should try to support multiple disks per virtio device. Otherwise, this patch looks good to me.
