Bug 879055

virt-manager version is "virt-manager-0.9.0-14.el6.x86_64" 
Red Hat Enterprise Linux Server release 6.3 (Santiago)

*** Bug 879054 has been marked as a duplicate of this bug. ***

1. Setting up a bond interface by virt-manager API

Can you provide some more details on what you're doing?

Hi, I meant, GUI not API, it was my mistake, sorry about that. 

I have used these steps : 
Open virt-manager >> Virtual Networks >> Add >> Bonding Interfaces 'option'

virt-manager-0.9.0-14.el6.x86_64

Can you reproduce that with 'virt-manager --debug' and attach the output?  This might go as down as netcf.

Created attachment 732264 [details]
log file with virt-manager --debug

I can reproduce this bug on RHEL6.4, and add the log file "virt-manager.log" with virt-manager --debug to attachment.

This looks like the same problem as bug #921621, So I'm reassigning to netcf.

I can still reproduce this issue with:
netcf-libs-0.1.9-4.el6_5.2.x86_64
virt-manager-0.9.0-21.el6.x86_64
libvirt-0.10.2-34.el6.x86_64

Steps to Reproduce:
 1. # service NetworkManager stop
 2. #virt-manager --debug -> Edit -> Connection details -> Network Interface -> "+"(Add) -> "Interface type"-> "Bond" -> Forward
 3. Configure the bond like this:
    Start mode: hotplug
    Active now:  check on
    IP setting: IPv4: DHCP
     Choose interfaces to bond:  eth0.
   Click "Finish"
 4. An error will popup like this:
 Error creating interface: 'Could not create interface: internal error failed to create (start) interface bond0: failed to execute external program -     Running 'ifup bond0' failed with exit code 1: ./network-functions: line 457: /sys/class/net/bond0/bonding/'mode: No such file or directory

'

5.When I choose start mode "none" then I can create bond interface successfully,when I try to destroy the interface,error will show from virt-manager GUI:
XML error: bond interface misses the bond element

This is fixed upstream in the following commit:

commit 581ff3f252552cf5edc8e47c4a72667a39e133ba

    remove extraneous quotes from BONDING_OPTS
    
    This fixes: https://bugzilla.redhat.com/show_bug.cgi?id=798851
    
    For some unknown reason, the BONDING_OPTS setting in ifcfg files was
    being set with an extra set of single quotes. So, for example, instead of:
    
      BONDING_OPTS="mode=active-backup primary=eth1 miimon=100 updelay=10 use_carrier=0"
    
    we would get (e.g.):
    
      BONDING_OPTS="'mode=active-backup primary=eth1 miimon=100 updelay=10 use_carrier=0'"
    
    Even when there weren't any BONDING_OPTS to set, the ifcfg file would
    still get:
    
      BONDING_OPTS="''"
    
    Since the extra quotes are added in all cases, and are never needed,
    this patch just unconditionally removes them.

I can reproduce it on below version,detail steps as below.

Version:

But I can not reproduce it on the new version, verify the bug as below:

2. Verify it using virt-manager, follow comment 13's reproducible steps.
