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.

Red Hat Product Errata RHBA-2013:1655 0 normal SHIPPED_LIVE seabios bug fix and enhancement update 2013-11-20 21:53:16 UTC

Description Amos Kong 2012-12-19 04:12:32 UTC 
Description of problem:

As I said in https://bugzilla.redhat.com/show_bug.cgi?id=831273#c10

VMs after failure of network boot tries to boot from other devices even if the they are not selected, this problem also exists in seabios upstream.

Currently we would adjust the priority according boot_deivces parameter in seabios, the default priority is 9999. We can resolve this issue by ignoring boot dev if its priority is 9999.

Version-Release number of selected component (if applicable):
seabios-0.6.1.2-25.el6.x86_64

How reproducible:

Steps to Reproduce:
1. qemu-kvm -boot order=c rhel6.image.qcow2   (vm disk is non-bootable)
  
Actual results:
1. vm will try to boot from disk, and failed
2. vm also try to boot from un-selected network 

Expected results:
vm only try to boot from disk.

Test this bug as following version:
Host:
# uname -r
2.6.32-373.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.355.el6.x86_64

seabios-0.6.1.2-27.el6.x86_64

Guest:
2.6.32-373.el6.x86_64

Steps:
1.boot guest with " strict=on"
.. /usr/libexec/qemu-kvm -drive file=/home/test.qcow2,if=none,id=drive-ide0-0-0,format=raw,cache=none -device virtio-blk-pci,scsi=off,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -vnc :0  -monitor stdio -boot strict=on

Results:

Guest only boot from hard disk,if can not boot ,not tried boot other devices.


Attional info(other tests):
1.Boot guest with hard disk(bootindex=1),CDROM(bootindex=2) and " -boot strict=on".Guest tried boot from Hard disk-->CDROM

2.Boot guest with hard disk(bootindex=2 ),network(bootindex=3),CDROM(bootindex=1)and "-boot strict=on" Guest tried boot from CDROM-->Hard disk-->network

3.Because fix is only for New interface (bootindex), so only test with "bootindex".


According to above test ,this bug fixed.
