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 Hu Jianwei 2014-12-19 09:49:47 UTC 
Description of problem:
libvirt emitted a invalid option "-bootloader" to qemu-kvm

Version-Release number of selected component (if applicable):
libvirt-1.2.8-11.el7.x86_64
qemu-kvm-rhev-2.1.2-17.el7.x86_64

How reproducible:
100%

Steps to Reproduce:

[root@ibm-x3850x5-06 ~]# virsh dumpxml r7| grep bootloader -a4
  <vcpu placement='static'>2</vcpu>
  <resource>
    <partition>/machine</partition>
  </resource>
  <bootloader>/usr/bin/pygrub</bootloader>
  <bootloader_args>--append single</bootloader_args>
...

[root@ibm-x3850x5-06 ~]# virsh list --all
 Id    Name                           State
----------------------------------------------------
 -     r7                             shut off

[root@ibm-x3850x5-06 ~]# virsh start r7
error: Failed to start domain r7
error: internal error: process exited while connecting to monitor: qemu-kvm: -bootloader: invalid option


Actual results:
As shown above steps.

Expected results:
qemu-kvm does not support this option, so libvirt should not emit such option to qemu CLI.

Additional info:
[root@ibm-x3850x5-06 libvirt-1.2.8]# /usr/libexec/qemu-kvm -h | grep bootloader
[root@ibm-x3850x5-06 libvirt-1.2.8]#
[root@ibm-x3850x5-06 libvirt-1.2.8]#  < nothing output

commit 9aa316612aa74abf88b3eb97e1a0eda920dab94a
Author:     Ján Tomko <jtomko>
CommitDate: 2015-03-02 07:39:09 +0100

    Remove bootloader option from QEMU
    
    It was only supported by xenner (since commit 763a59d8),
    for which we removed support in commit de9be0a.
    
    Remove the code generating this command line option,
    refuse to parse it and delete the outdated tests.

Verify this bug with 
libvirt-1.2.17-2.el7.x86_64
qemu-kvm-rhev-2.3.0-9.el7.x86_64


1. Prepare xml file with bootload options.

# cat r7.xml |grep bootload -A 2 
  <bootloader>/usr/bin/pygrub</bootloader>
    <bootloader_args>--append single</bootloader_args>
  <clock offset='utc'/>

2. Try to define guest with above guest 

# virsh define r7.xml 
error: Failed to define domain from r7.xml
error: unsupported configuration: bootloader is not supported by QEMU


# /usr/libexec/qemu-kvm -h | grep bootloader
