The network object created can be seen in the debugger, the value for "mtu" is "0", when the default should be 1500. The web portal shows the default value is "1500". When I try to retrieve the default value, it returns 0. However, if the value is explicitly stated, then it can be retrieved: net = {NetworkContainer@4322} display = null dnsResolverConfiguration = null ip = null mtu = {BigInteger@4369} "0" profileRequired = null required = null status = null stp = {Boolean@4370} false usages = {ArrayList@4371} size = 0 vlan = {VlanContainer@4372} cluster = null dataCenter = {DataCenterContainer@4373} externalProvider = null externalProviderPhysicalNetwork = null networkLabels = {ArrayListWithHref@4374} size = 0 permissions = {ArrayListWithHref@4375} size = 0 qos = null vnicProfiles = {ArrayListWithHref@4376} size = 0 comment = "comment" description = "description" href = "/ovirt-engine/api/networks/cb3909d1-28e7-4ff1-aa97-858286e407a6" id = "cb3909d1-28e7-4ff1-aa97-858286e407a6" name = "network1"
