Description Dale Bewley 2009-11-11 18:01:22 UTC

Description of problem:
When the kernel bridge module is not loaded the ncftool fails to run. Tool runs after 'modprobe bridge'. 

Guests will not normally have bridge module loaded, but I would expect ncftool to simply drop bridge support and continue to run in the case where kernel bridging is not available.

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

Linux f12-beta 2.6.31.5-127.fc12.x86_64 #1 SMP Sat Nov 7 21:11:14 EST 2009 x86_64 x86_64 x86_64 GNU/Linux

netcf-0.1.4-1.fc12.x86_64

How reproducible:

Every time

Steps to Reproduce:
1. install f12 guest
2. yum install netcf
3. ncftool
  
Actual results:

[root@f12-beta ~]# ncftool
Failed to initialize netcf
error: File operation failed
error: can not open /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory

Expected results:
[root@f12-beta ~]# modprobe bridge
[root@f12-beta ~]# ncftool
ncftool> quit
