Now we have virtio-pci, we can make the virt board's default block device type be IF_VIRTIO. This allows users to use simplified command lines that don't have to explicitly create virtio-pci-blk devices; the -hda &c very short options now also work. This means we also need to set no_cdrom to avoid getting a default cdrom device -- this is needed because the virtio-blk device will fail if it is connected to a block backend with no media, which is what the default cdrom device typically is. Providing a cdrom with media via -cdrom will succeed, but silently create a device with non-removable medium. this is probably not really what the user wants, but is the best we can do now. Note that this change means that some command lines which used to work (by accident) will stop working. Where a drive was connected manually to a device but without 'if=none' being specified, we used to treat this as an IDE drive, which we would then not autoplug because the board doesn't support IDE. Now we will treat it as a virtio disk and autoplug it, which means the attempt to use the drive manually will fail: qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already in use because it has been automatically connected to another device (did you need 'if=none' in the drive options?) The command line will have to be changed to include 'if=none', as the error message suggests.
