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 Paolo Bonzini 2012-03-21 08:56:46 UTC 
+++ This bug was initially created as a clone of Bug #805413 +++

Description of problem:
KVM supports booting from host USB devices (both directly attached and redirected over IP).  However, it does not support assigning a boot index to them.

Version-Release number of selected component (if applicable):
0.9.10

How reproducible:
100%

Steps to Reproduce:
1. Here is a sample command line for the usb-host case:
x86_64-softmmu/qemu-system-x86_64 -nodefaults -vga cirrus -readconfig ich9-ehci-uhci.cfg -device usb-host,bus=ehci.0,vendorid=0x0a16,productid=0x2499,bootindex=2 /path/to/disk.img -boot menu=on
2.
3.
  
Actual results:
Error "Property 'usb-host.bootindex' not found"

Expected results:
USB host device comes second in the boot menu
Comment 2 Paolo Bonzini 2012-03-21 13:07:25 UTC 
<boot order='...'/> already supported for PCI assigned devices.
Comment 4 Paolo Bonzini 2012-07-20 13:36:52 UTC 
The QEMU bug was moved to RHEL7, so moving this one too.
Comment 7 Ján Tomko 2012-11-16 15:33:49 UTC 
Boot order for USB hostdev devices works upstream:

    qemu: add bootindex for usb-host and usb-redir devices

however usb-redir will require more work. Documentation and tests will follow after that.
