[Qemu-devel] [Bug 1155403] Re: virtio cdrom detected as hard disk

[Paolo Bonzini]

if=virtio means virtio-blk, not virtio-something.

Also, Linux is perfectly fine with ISO images on virtio, the Ubuntu
installer is  wrong in not scanning virtio disks. Since Ubuntu wouldn't
work either way, they should first fix the installer and then we can re-
evaluate if QEMU can do something (probably not, except warning for
media=cdrom).

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?
