Bug 1019695

Created attachment 812833 [details]
engine

Description of problem:
When trying to attach network with custom MTU on BOND interface the operation succeed but engine can't see the new network configuration (on VDSM the bond with the network created as it should)
When opening setupNetwork again the BOND is not there and the network is unattached.

This cause required network to be non-operational (Attach required network to BOND interface and from engine side this network is not attached to any interface)

Version-Release number of selected component (if applicable):
vdsm-4.10.2-27.0.el6ev.x86_64
rhevm-3.2.4-0.44.el6ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. Create net_mtu network with MTU 9000
2. Open setupNetworks, create BOND and attach net_mtu to the BOND

Actual results:
The BOND with the network is not in setupNetworks.

Expected results:
The BOND with the attached network should be in setupNetworks.
