Why do you say that?  I would say that virtio means use
paravirtualized IO rather than emulating some real hardware.  Whether
that ends up being done with virtio-blk, or virtio-scsi is an
implementation detail.  The media argument seems a perfectly natural
way to select between the two.

Title:
  virtio cdrom detected as hard disk

Status in QEMU:
  Invalid
Status in “debian-installer” package in Ubuntu:
  New
Status in “qemu” package in Ubuntu:
  Invalid

Bug description:
  Trying to install Ubuntu or Debian using virtio to emulate the cdrom
  fails.  This appears to be due to the drive appearing to be a hard
  disk, rather than a cdrom, despite the media=cdrom argument to qemu.

  I'm not sure if this is a bug in qemu, or the kernel virtio driver?
