Summary: SCSI: Windows (XP) Full Format fails to complete on SCSI
Initial Comment:
Basically "Full Format" fails on SCSI disk.
Tested on:
KVM 60-x series up to KVM-77
Host: F7/x64, Intel CPU
KVM: KVM-77
Guest OS: Windows XP, 32-bit
Quick format succeeds and OS can be installed only that way.
Since Linux uses quick format, and does not have Full Format capability AFAIK,
Linux guests can be installed successfully.
Qemu command:
/usr/local/bin/qemu-system-x86_64 -m 256 -cdrom
/isos/windows/WindowsXP-sp2-vlk.iso -boot d -drive
file=/vm/xp-scsi-test.qcow2,if=scsi,boot=on -name WindowsXP-scsi-test

Message:
I can't seem to attach files. They have been emailed to lvivier. The
summary is:
Quick Format: No errors or unknown SCSI commands. Yet the Windows format
still fails somehow.
Full Format: Lots of:
scsi-disk: Unknown SCSI command (2f)
scsi-disk: Command complete tag=0x100fd sense=5
scsi-disk: Command: lun=0 tag=0x100fd data=0x2f 0x00 0x00 0x01 0x32 0x3f
0x00 0x00 0x20 0x00
scsi-disk: Unknown SCSI command (2f)
scsi-disk: Command complete tag=0x100fd sense=5
scsi-disk: Command: lun=0 tag=0x100fd data=0x2f 0x00 0x00 0x01 0x32 0x3f
0x00 0x00 0x20 0x00
(after which I gave up and didn't bother waiting for it to finish)

Message:
I'm not able to reproduce this issue. Could you uncomment DEBUG_SCSI in
qemu/hw/scsi-disk.c and retest ?

Message:
Confirmed with quick format option too. No debug logs yet. Certainly
nothing appears on QEMU stdio. Will try to attach a screenshot at least.
Tested: kvm-75 and kvm-77
Host: Intel CPU, Ubuntu 8.04 amd64
Guest: Windows XP, x64 Edition

Message:
Alexey,
Can you provide more details on the failure? Is it a hang, or the Windows
SCSI driver complains?
Are there error messages on the QEMU stdio?
Other than that, the debug output Laurent asked for.
>From what I recall full format works (or at least used to) on W2003. Will
retest.

Message:
latest KVM introduces latest qemu.
In this release of qemu SCSI commandz return status has been corrected, so
unimplemented commands were silently ignored whereas now they return
errors.
The solution is easy: modify the code to ignore the faulty SCSI command, I
did this for instance for VERIFY.
Could you activate debug in hw/scsi-disk.c and send me logs ?
