Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Gleb Natapov 2010-10-17 11:18:31 UTC 
We need to allow to specify boot order from qemu command line to have better control of a guest behaviour. Qemu should build list of all bootable devices and pass the preferred order into Seabios.
Comment 10 Keqin Hong 2011-02-11 10:49:03 UTC 
Verified on qemu-kvm-0.12.1.2-2.144.el6.x86_64 and seabios-0.6.1.2-3.el6.x86_64. PASS.

Steps:
1. Decide boot order for multiple block and NIC devices
2. Boot by passing boot order decided
3. Change boot order, and repeat step 1 and step 2

CLI e.g.
/usr/libexec/qemu-kvm -drive file=disk1.img,if=none,id=disk1 \
  -device ide-drive,drive=disk1,bootindex=4 \
  -drive file=disk2.img,if=none,id=disk2 \
  -device virtio-blk-pci,drive=disk2,bootindex=3 \
  -netdev tap,id=net0 -device virtio-net-pci,netdev=net0,mac=xxxx,bootindex=2 \
  -netdev tap,id=net1 -device e1000,netdev=net1,mac=yyyy,bootindex=1 \
  -drive file=OS.iso,if=none,id=os,media=cdrom,format=raw \
  -device ide-drive,drive=os,id=ide0-0-1,bootindex=0 \
  -drive if=none,file=fda.img,id=fda -drive if=none,file=fdb.img,id=fdb \
  -global isa-fdc.bootindexB=30 -global isa-fdc.bootindexA=40
