[ovirt-devel] PROBLEM: Unable to retrieve value for MTU when default is used

I'm trying to automate a test which checks that the default values are being set correctly when adding a network to a host. When I create a network without specifying a value for the MTU, I can see from the web UI that the default value (1500) is being used. When I try to retrieve this MTU value from the SDK to ensure it is set correctly, the value returned is '0'. The same issue is not occurring if I explicitly set the MTU value when creating the network. When the MTU value is assigned, instead of using the default value, it is possible to retrieve it from the SDK correctly. Is there any way I can retrieve the value for MTU from the SDK when the default is used?
