[Pavan Naregundi]

When tried to boot the rhel5.4 guest with the below mentioned options,

/usr/local/bin/qemu-system-x86_64 -drive file=test_rhel5.4.raw,if=scsi -m 512 -enable-kvm

Boot failed with following error,
-------------------------------------

This guest was installed with following options,
# /usr/local/bin/qemu-system-x86_64 -drive file=test_rhel5.4.raw,if=scsi -net nic,model=rtl8139 -cdrom /var/RHEL5.4-Server-20090819.0-i386-DVD.iso -m 512 -enable-kvm

Steps to reproduce:
1. Install a guest with scsi drive interface
2. After the install boot the guest with scsi interface. We can see the above mentioned boot failure.

Can you reproduce this with qemu 0.12?

[Francesco Salbaroli (thewathrog)]

Yes, I had the problem also using qemu 0.12.3.

Could finish installing the OS using virt-install with distribution
specific parameters for RHEL5.4+

QEMU does not support booting from SCSI. 0.13.0 will add support for booting from virtio in addition to IDE.

[Gerd Hoffmann (kraxel-redhat)]

Oh, scsi boot actually works.
You need 0.12.4+ or unstable.
Also http://www.lsi.com/DistributionSystem/AssetDocument/files/support/ssp/sdms/Bios/lsi_bios.zip
Unpack the downloaded zip to get the option rom.
Then boot qemu with -option-rom 8xx_64.rom

[Anthony Liguori (anthony-codemonkey)]

Wow, I'm amazed that works. That said, it doesn't look like that blob is redistributable.

Hello,

Is there any plans to fix this issue?

lsi_scsi: error: ORDERED queue not implemented
lsi_scsi: error: Unimplemented message 0x0d
kvm: /build/buildd/qemu-kvm-0.12.5+noroms/hw/lsi53c895a.c:596: lsi_reselect: Assertion `s->current == ((void *)0)' failed.

I've tried with qemu-kvm: 012.4 and

I get this error all the time!
If I start to have intensive I/O (like copy really large files), it just crashes!

The crashes were most likely fixed by commit e8637c9013609271772cc0c3436cb1240cd6b034 , which is a part of 0.13 and while it applies to 0.12 just fine, it didn't went into 0.12-stable.
