[Qemu-devel] [Bug 611142] Re: seabios should have native scsi support

[Scott Moser]

I just did some bug cleanup work here.
  Per Michael's comment, this is now fixed in seabios.  So I marked the seabios 
task as fix-released in Ubuntu.
  12.04 will not have this fix present, as its seabios is 0.6.2, but versions 
of ubuntu 12.10 (quantal) and later should be fix-released.

Note, I did not test this.

** No longer affects: qemu

** No longer affects: qemu-kvm (Ubuntu)

** Changed in: seabios (Ubuntu)
       Status: Confirmed => Fix Released

Title:
  seabios should have native scsi support

Status in “seabios” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: seabios

  Currently when a grub multiboot image is booted with 'kvm -kernel' and
  'biosdisk' module, it will see block devices of type IDE or virtio.
  It will not see scsi devices.

  To demonstrate this:
  $ qemu-img create -f qcow2 disk.img 1G
  $ grub-mkrescue --output=rescue.iso
  $ grub-mkimage -O i386-pc --output=grub-mb.img biosdisk minicmd part_msdos

  An 'ls' inside the grub prompt will show hard disks (hd0) on if:
  a.) -drive uses interface of virtio or scsi
  or
  b.) kvm boots boot from a cdrom or floppy 

  For example, with these commands, grub will see a '(hd0)'
  $ kvm -drive file=disk.img,if=scsi,boot=on -cdrom rescue.iso -boot d
  $ kvm -drive file=disk.img,if=scsi,boot=on -floppy rescue.iso -boot a
  $ kvm -drive file=disk.img,if=virtio,boot=on -cdrom rescue.iso -boot d
  $ kvm -drive file=disk.img,if=ide,boot=on -cdrom rescue.iso -boot d
  $ kvm -drive file=disk.img,if=virtio,boot=on -kernel grub-mb.img 
  $ kvm -drive file=disk.img,if=ide,boot=on -kernel grub-mb.img 

  But the following will not:
  $ kvm -drive file=disk.img,if=scsi,boot=on -kernel grub-mb.img
