Description Xu Han 2013-10-08 23:00:57 EDT
Description of problem:
qemu-kvm man page guide wrong path for qemu-bridge-helper.

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

How reproducible:

Steps to Reproduce:
1.open man page and find string 'qemu-bridge-helper'

Actual results:
If running QEMU as an unprivileged user, use the network helper
helper to configure the TAP interface. The default network helper
executable is /usr/local/libexec/qemu-bridge-helper.

Expected results:
The default path is /usr/libexec.

Additional info:
Comment 2 Amos Kong 2013-10-14 02:00:05 EDT
[root@amosk qemu]# ls /usr/local/libexec/qemu-bridge-helper -l
-rwxr-xr-x 1 root root 24198 Oct 14 13:58 /usr/local/libexec/qemu-bridge-helper

qemu-bridge-helper will be truly installed to '/usr/local/libexec/', it's expected, so not a bug of manpage
Comment 4 Amos Kong 2013-10-14 12:05:52 EDT
qemu-bridge-helper of rhel7 is not consistent with manpage.
Better to update redhat/qemu-kvm.spec to make it same as upstream.
Comment 6 Amos Kong 2013-10-22 08:47:55 EDT
The DEF() C macro in this file uses DEFAULT_BRIDGE_HELPER.  In texi mode
the C preprocessor is not used so DEFAULT_BRIDGE_HELPER is not

upstream needs to be fixed.
Comment 7 Amos Kong 2013-10-28 12:32:21 EDT
Posted another fix to upstream:
Comment 10 Miroslav Rezanina 2013-11-28 02:35:46 EST
Fix included in qemu-kvm-1.5.3-20.el7
Comment 12 Xu Han 2013-12-09 04:02:39 EST
Verify this bug with component:

1. check patch.
# rpm -q qemu-kvm --changelog | grep '1016952'

2. check string 'qemu-bridge-helper' in man page.
# man qemu-kvm | grep 'qemu-bridge-helper'

after step1,
# rpm -q qemu-kvm --changelog | grep 1016952
- kvm-doc-fix-hardcoded-helper-path.patch [bz#1016952]
- Resolves: bz#1016952

after step2,
# man qemu-kvm | grep 'qemu-bridge-helper'
           executable is /path/to/qemu-bridge-helper.
                   -net nic -net tap,"helper=/path/to/qemu-bridge-helper"
           /path/to/qemu-bridge-helper and the default bridge device is br0.

Base on these test results above, this bug has been fixed.
