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

    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    refuse to parse it and delete the outdated tests.

Comment 8 Shanzhi Yu 2015-07-16 07:44:05 UTC
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
