Fix missing vlan/bond/ethernet info in dumpxml --live
This patch addresses:
https://bugzilla.redhat.com/show_bug.cgi?id=736920
https://bugzilla.redhat.com/show_bug.cgi?id=739505
Commit 38f44cf (pushed between 0.1.8 and 0.1.9) put a check for an
invalid ifindex into the functions that add type-specific status data
to the xml document (e.g. the mac address of an ethernet, or tag of a
vlan). This check was inadvertently done incorrectly ("ifindex !=
RTNL_LINK_NOT_FOUND" rather than "ifindex == RTNL_LINK_NOT_FOUND").
This patch corrects that error.
Because these functions are a part of the code to gather info from the
kernel via libnl (netlink) calls, there is unfortunately no simple way
to incorporate a build-time test to prevent similar regressions in the
future; we will instead have to rely on separate testing.

A fix for this bug is available in a new netcf build for RHEL6: https://brewweb.devel.redhat.com/buildinfo?buildID=180923 tested with
libvirt-0.9.4-13.el6.x86_64
netcf-0.1.9-2.el6.x86_64
Steps:
1.Create a file with content below, assuming the name is bond0.xml:
<interface type='bond' name='bond0'>
<start mode='none'/>
<protocol family='ipv4'>
<dhcp/>
</protocol>
<bond mode='active-backup'>
<miimon freq='100' updelay='10' carrier='ioctl'/>
<interface type='ethernet' name='eth0'>
</interface>
<interface type='ethernet' name='eth1'>
</interface>
</bond>
</interface>
2.stop NetworkManager service
# service NetworkManager stop
and restart network service.
# service network restart
3.Define new bond0
# virsh iface-define bond0.xml
# virsh iface-start bond0
4. Check the new bond0
# virsh iface-dumpxml bond0
<interface type='bond' name='bond0'>
<bond>
<interface type='ethernet' name='eth0'>
<mac address='00:21:9b:57:9f:58'/>
</interface>
<interface type='ethernet' name='eth1'>
<mac address='00:21:9b:57:9f:59'/>
</interface>
</bond>
</interface>

Description of problem: Command "virsh iface-dumpxml ..." will got an error like "error: XML error: bond interface misses the bond element" when we want to check the bond interface's xml file. It happened when netcf's version is 0.1.9-1. The version of 0.1.8-1 and 0.1.7-1 have no this problem. Version-Release number of selected component (if applicable): libvirt-0.9.4-10.el6.x86_64 netcf-0.1.9-1.el6.x86_64 How reproducible: always Steps to Reproduce: Need two NIC, eth0 and eth1 1.Create a file with content below, assuming the name is bond0.xml: <interface type='bond' name='bond0'> <start mode='none'/> <protocol family='ipv4'> <dhcp/> </protocol> <bond mode='active-backup'> <miimon freq='100' updelay='10' carrier='ioctl'/> <interface type='ethernet' name='eth0'> </interface> <interface type='ethernet' name='eth1'> </interface> </bond> </interface> 2.stop NetworkManager service # service NetworkManager stop and restart network service. # service network restart 3.Define new bond0 # virsh iface-define bond0.xml # virsh iface-start bond0 4. Check the new bond0 # virsh iface-dumpxml bond0 Actual results: Actually, we will got "error: XML error: bond interface misses the bond element" Expected results: Show the detail information about the bond0. It should be the same with bond0.xml. Additional info:
