Description Sibiao Luo 2013-04-02 08:55:40 UTC
Description of problem:
boot a pre-installed virtio-scsi vm under Q35, and attach a usb storage using the ehci+uchi companion config file, set usb-storage's bootindex to 1, virtio-scsi's to 2, but seabios always try to boot from virtio-scsi instead of usb-storage.
BTW, i test it with pc-i440fx-1.4 machine type did not hit it.

Version-Release number of selected component (if applicable):
host info:
kernel-3.9.0-0.rc4.45.el7.x86_64
qemu-kvm-1.4.0-1.el7.x86_64
seabios-1.7.2-0.2.gita810e4e7.el7.x86_64
guest info:
windows: win2012/win8 64bit
rhel7:   kernel-3.9.0-0.rc4.45.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot a guest with a simulated usb-storage using ehci controller under Q35.
e.g:# /usr/libexec/qemu-kvm -S -M q35 -cpu SandyBridge -enable-kvm -m 4096 -smp 2,sockets=2,cores=1,threads=1 -no-kvm-pit-reinjection -name sluo-test -uuid ed09fa10-6ffe-4811-a42f-0294afcb5a42 -rtc base=localtime,clock=host,driftfix=slew -readconfig /home/ich9-ehci-uhci.cfg -device usb-tablet,id=tablet,port=1 -device usb-hub,id=hub,port=2 -device usb-kbd,id=kbd,port=2.1 -device usb-mouse,id=mouse,port=2.2 -drive file=/home/my-usb-storage1.qcow2,if=none,id=storage1,media=disk,cache=none,format=qcow2 -device usb-storage,drive=storage1,id=usb-storage1,bootindex=1 -drive file=/home/windows_server_2012_x64.qcow2,if=none,id=drive-system-disk,format=qcow2,cache=none,aio=native,werror=stop,rerror=stop,serial=QEMU-DISK1 -device virtio-scsi-pci,bus=pcie.0,addr=0x3,id=scsi0 -device scsi-hd,bus=scsi0.0,drive=drive-system-disk,id=system-disk,bootindex=2 -netdev tap,id=hostnet0,vhost=off,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=08:2e:5f:0a:0d:b1,bus=pcie.0,addr=0x4,bootindex=3 -device virtio-balloon-pci,id=ballooning,bus=pcie.0,addr=0x5 -qmp tcp:0:4444,server,nowait -k en-us -boot menu=on -vnc :1 -spice disable-ticketing,port=5931 -monitor stdio
2.press F12 during POST.

Actual results:
after step 2, seabios always try to boot from virtio-scsi instead of usb-storage.
1. virtio-scsi Drive QEMU QEMU HARDDISK 1.4.
2. USB MSC Drive QEMU QEMU HARDDISK 1.4.
3. Legacy option rom
4. Floppy [drive A]
5. iPXE (PCI 00:05.0)

Expected results:
seabios could boot from usb-storage first as specified it firstly in command line.

Created attachment 730665 [details]
screenshot for testing under pc-i440fx-1.4, the usb-storage's boot priority is set correctly by seabios.

Comment 3 Sibiao Luo 2013-04-02 09:08:27 UTC
BTW, the network also have to same problem to usb-storage, in the comment #0, i set the network's bootindex=3, but the seabios display it to '5'. this issue only under the Q35, pc-i440fx-1.4 machine type have no such issue.

Comment 4 Gerd Hoffmann 2013-07-24 07:49:46 UTC
IIRC this one was fixed in qemu by mst (fix pcihost name in device path).

Comment 5 Amos Kong 2013-11-07 03:16:41 UTC
sluo, can you test with latest qemu-kvm-rhel7?
It seems a same issue as bug 923030.

Yes, the bootindex is just as specified in command line correctly with the same test as comment #0.

host info:
3.10.0-41.el7.x86_64
qemu-kvm-1.5.3-14.el7.x86_64
seabios-1.7.2.2-3.el7.x86_64
seabios-bin-1.7.2.2-3.el7.noarch

after step 2,
1. USB MSC Drive QEMU QEMU HARDDISK 1.5.    <------USB storage
2. virtio-scsi Drive QEMU QEMU HARDDISK 1.5.<------scsi system disk
3. iPXE (PCI 00:04.0)                       <------virtio nic
4. Legacy option rom
5. Floppy [drive A]

Base on above, this issue also has been fixed with qemu-1.5.1 in bug 923030.

Best Regareds,
sluo
