Please note there is no the bug problem for pc machine type.

I can reproduce the problem on rhel7.4 ((qemu) info version 2.9.0 (v2.9.0-191-g1ef7054)) as well. The key point is to keep exactly the same architecture when switching between virtio and usb attached storage. For example, WS2012R2 VM installed with the following command line

sudo $QEMU -enable-kvm -machine q35 -device pcie-root-port,bus=pcie.0,id=root0,multifunction=on,chassis=1,addr=0xa.0 -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=root0 -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=qcow2,file=/home/vrozenfe/work/images/$IMAGE -device scsi-hd,id=image1,drive=drive_image1,bootindex=1 -cpu Opteron_G4,+kvm_pv_unhalt,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time -m 1G -smp 2 -cdrom /run/media/vrozenfe/elements/isos/en_windows_server_2012_r2_x64_dvd_2707946.iso -fda /home/share/builds/virtio-win-1.9.3-1.el7/usr/share/virtio-win/virtio-win_amd64.vfd -boot dc -monitor stdio

will crash into INACCESSIBLE_BOOT_DEVICE BSOD later when switching to usb disk

sudo $QEMU -enable-kvm -machine q35 -device pcie-root-port,bus=pcie.0,id=root0,multifunction=on,chassis=1,addr=0xa.0 -device nec-usb-xhci,id=usbtest,bus=root0 -drive id=drive_image1,if=none,snapshot=off,aio=threads,cache=none,format=qcow2,file=/home/vrozenfe/work/images/$IMAGE -device usb-storage,id=image1,drive=drive_image1,bus=usbtest.0,bootindex=1 -cpu Opteron_G4,+kvm_pv_unhalt,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time -m 1G -smp 2 -monitor stdio

but survives the same configuration with "-smp 3" instead of "-smp 2". And of course the VM can be booted successfully into "safe mode" 

Gu Nini, could you please repeat the same experiment on you setup to see that it is not a regression first of all?

Thanks,
Vadim.

I could reproduce the bug on the original rhel7.4 qemu-kvm-rhev version this time, so the bug is not a regression, clear the keyword.

Thanks for the analysis.

Hi all,
recently I test one case RHEL7-8979 - [usb-device] [usb-storage] Usb device bootindex test, and reproduce this issue again in rhel-7.6

host info:
kernel-3.10.0-915.el7.x86_64 & qemu-img-rhev-2.12.0-7.el7.x86_64
guest info:
windows 2016 and scsi-image

Looking forward the bug fixed soon

Regards,
Li Xiaohui

Hi all:
I test case RHEL7-8979: [usb-device] [usb-storage] Usb device bootindex test, reproduce this bug in win2016 guest for rhel8 host, and guest machine type is pc


version info:
host info:
kernel-4.18.0-8.el8.x86_64 & qemu-img-2.12.0-31.el8+1812+3c9feb68.x86_64 &
virt-viewer-7.0-1.el8.x86_64
guest info:
kernel-4.18.0-8.el8.x86_64


steps:
1.install win2016 guest with virtio-blk
/usr/libexec/qemu-kvm -M pc \
-cpu SandyBridge \
-enable-kvm \
-m 2G \
-smp 4 \

-vnc :4 \
-monitor stdio \

2.boot guest with usb-storage:
/usr/libexec/qemu-kvm -M pc \
-cpu SandyBridge \
-enable-kvm \
