I guess the best way to make this work would be to get the original option rom for the emulated LSI SCSI controller licensed so that we can use it freely. That way we
a) verify that the emulation is correct b) are even closer to real world hardware The difficult thing here is on how to talk to LSI. -- seabios should have native scsi support https://bugs.launchpad.net/bugs/611142 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: New Status in “qemu-kvm” package in Ubuntu: New Status in “seabios” package in Ubuntu: New 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 ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: seabios 0.6.0-0ubuntu1 ProcVersionSignature: User Name 2.6.32-305.9-ec2 2.6.32.11+drm33.2 Uname: Linux 2.6.32-305-ec2 i686 Architecture: i386 Date: Thu Jul 29 03:21:21 2010 Dependencies: Ec2AMI: ami-e930db80 Ec2AMIManifest: ubuntu-images-testing-us/ubuntu-maverick-daily-i386-server-20100727.manifest.xml Ec2AvailabilityZone: us-east-1b Ec2InstanceType: m1.small Ec2Kernel: aki-407d9529 Ec2Ramdisk: unavailable PackageArchitecture: all ProcEnviron: PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: seabios
