RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Sibiao Luo 2013-03-19 03:37:17 UTC 
Description of problem:
Install guest with passthrough host CD-ROM using scsi-block in Q35, the seabios fail to assign correct order for the boot device in seabios as we specified the bootindex in qemu-kvm command line.
BTW, if use the pc-i440fx-1.4 emulated machine for -M, it have no such issue.

Version-Release number of selected component (if applicable):
host info:
kernel-3.8.0-0.40.el7.x86_64
qemu-kvm-1.4.0-1.el7.x86_64
seabios-bin-1.7.2-0.2.gita810e4e7.el7.noarch
seabios-1.7.2-0.2.gita810e4e7.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Install guest with passthrough host CD-ROM using scsi-block in Q35, and specify the bootindex in cli.

2.press F12 during POST.
  
Actual results:
after step 2, we can see the order of boot device as following， i will attach the screenshot later.
Press F12 for boot menu.

Select boot device:

1. virtio-scsi Drive QEMU QEMU HARDDISK 1.4.
2. Legacy option rom
3. Floppy [drive A]
4. DVD/CD [AHCI/5: QEMU DVD-ROM ATAPI-4 DVD/CD]
5. DVD/CD [virtio-scsi Drive QEMU QEMU CD-ROM 1.4.]
6. iPXE (PCI 00:06.0)

Expected results:
the order of the boot device in seabios should the same to we specified the bootindex in qemu-kvm command line.
Press F12 for boot menu.

Select boot device:

1. DVD/CD [virtio-scsi Drive QEMU QEMU CD-ROM 1.4.]
2. virtio-scsi Drive QEMU QEMU HARDDISK 1.4.

Sorry, the correct expected results should be as following:

Press F12 for boot menu.

Select boot device:

1. DVD/CD [virtio-scsi Drive QEMU QEMU CD-ROM 1.4.] <-------------for passthrough host CD-ROM
2. virtio-scsi Drive QEMU QEMU HARDDISK 1.4.        <-------------for system
3. iPXE (PCI 00:06.0)
4. DVD/CD [AHCI/5: QEMU DVD-ROM ATAPI-4 DVD/CD]     <-------------for whql driver
5. Legacy option rom

Comment 6 Amos Kong 2013-05-28 11:54:03 UTC 
The fw_dev_paths to seabios by qemu:

/q35-pcihost@i0cf8/scsi@4/channel@0/disk@0,0
/q35-pcihost@i0cf8/ethernet@2/ethernet-phy@0
/q35-pcihost@i0cf8/pci8086,2922@1f,2/drive@5/disk@0
/q35-pcihost@i0cf8/ethernet@3/ethernet-phy@0


but we only match '/pci@i0cf8', this should be fixed in seabios.

Comment 7 Amos Kong 2013-05-28 12:11:03 UTC 
Applied above patch, bootindex of nic/ide-disk works.
bootindex of scsi-disk still doesn't work (I already fixed the bz 967444 in qemu), it seems another seabios issue.

> Applied above patch, bootindex of nic/ide-disk works.

Take this to me. I already posted patches  to (qemu & seabios) upstream.

[QEMU PATCH] pci: change typename of q35 to pci-q35 
[SeaBIOS PATCH v2] boot: fix fw_dev_path pattern to match q35

It caused by my dirty patch queue, no other issue with scsi.

Comment 12 Sibiao Luo 2013-11-18 05:42:05 UTC 
verify this issue on qemu-kvm-1.5.3-19.el7.x86_64 with the same steps that did not met such issue any more, so this issue has been fixed correctly.

host info:
3.10.0-41.el7.x86_64
qemu-kvm-1.5.3-19.el7.x86_64
seabios-1.7.2.2-4.el7.x86_64

Results:
It has correct boot device bootindex as specified in cli.

Best Regards,
