Currently, oVirt limits the names of its networks to 15 alphanumeric characters. This limitation dates back to the ages where all networks were VM network, all were implemented by a Linux bridge, and the same name was used to identify the network and the Linux bridge implementing it on each host. That has to change. 15 characters are not enough for humans; spaces, and other special characters are visually useful, and non-English speaking users would love to use their native alphabet in network names. For this reason network names are allowed to consist of 256 Unicode characters. If a Linux bridge is created, the name is created from the network name, if it is suitable, or from the network's uuid.
This RFE need some additional work - - Issue 1 - When creating names like - gggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg tttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt Engine fails to create vNIC profiles to such networks with internal server error: 2017-08-06 08:23:47,804+03 ERROR [org.ovirt.engine.core.bll.network.vm.AddVnicProfileCommand] (default task-8) [6148f74c-7bf4-4cd6-b1b8-6fedc73f30e8] Exception: org.springframework.dao.DataIntegrityViolationExcept ion: CallableStatementCallback; SQL [{call insertvnicprofile(?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}]; ERROR: value too long for type character varying(50) Where: SQL statement "INSERT INTO vnic_profiles ( id, name, network_id, network_qos_id, port_mirroring, passthrough, migratable, custom_properties, description, network_filter_id ) VALUES ( v_id, v_name, v_network_id, v_network_qos_id, v_port_mirroring, v_passthrough, v_migratable, v_custom_properties, v_description, v_network_filter_id )" - Issue 2 - When creating long names with special characters(@#$%^&*) for example: test-netw-123456-%5#@%&*()_+=1111111 test-net-@#$%^&*( test55555555555@ Engine doesn't show and recognize those profiles in the VM's vNIC drop down list.
