The most +important changes are discussed below. + +Paths to DPDK, OVS and QEMU +=========================== + +VSPERF uses external tools for proper testcase execution. Thus it is important +to properly configure paths to these tools. In case that tools are installed +by installation scripts and are located inside ``./src`` directory inside +VSPERF home, then no changes are needed. On the other hand, if path settings +was changed by custom configuration file, then it is required to update configuration +accordingly. Please check your configuration files for following configuration +options: + +.. code:: bash + + OVS_DIR + OVS_DIR_VANILLA + OVS_DIR_USER + OVS_DIR_CUSE + + RTE_SDK_USER + RTE_SDK_CUSE + + QEMU_DIR + QEMU_DIR_USER + QEMU_DIR_CUSE + QEMU_BIN + +In case that any of these options is defined, then configuration must be updated. +All paths to the tools are now stored inside ``PATHS`` dictionary. Please +refer to the paths-documentation_ and update your configuration where necessary. + +.. _paths-documentation: http://artifacts.opnfv.org/vswitchperf/docs/index.html#configuration-of-paths-dictionary + +Configuration change via CLI +============================ + +In previous releases it was possible to modify selected configuration options +(mostly VNF specific) via command line interface, i.e. by ``--test-params`` +argument. This concept has been generalized in Danube release and it is +possible to modify any configuration parameter via CLI or via **Parameters** +section of the testcase definition. Old configuration options were obsoleted +and it is required to specify configuration parameter name in the same form +as it is defined inside configuration file, i.e. in uppercase. Please +refer to the overriding-parameters-documentation_ for additional details. + +**NOTE:** In case that execution of VSPERF is automated by scripts (e.g. for +CI purposes), then these scripts must be checked and updated too. It means, +that any occurrence of + +.. code:: bash + + guest_loopback + vanilla_tgen_port1_ip + vanilla_tgen_port1_mac + vanilla_tgen_port2_ip + vanilla_tgen_port2_mac + tunnel_type + +shall be changed to the uppercase form and data type of entered values must +match to data types of original values from configuration files. + +In case that ``guest_nic1_name`` or ``guest_nic2_name`` is changed, +then new dictionary ``GUEST_NICS`` must be modified accordingly. +Please see guest-configuration_ and ``conf/04_vnf.conf`` for additional +details. + +.. _overriding-parameters-documentation: http://artifacts.opnfv.org/vswitchperf/docs/index.html#overriding-values-defined-in-configuration-files +.. _guest-configuration: http://artifacts.opnfv.org/vswitchperf/docs/index.html#configuration-of-guest-options + +Traffic configuration via CLI +============================= + +In previous releases it was possible to modify selected attributes of generated +traffic via command line interface. This concept has been enhanced in Danube +release and it is now possible to modify all traffic specific options via +CLI or by ``TRAFFIC`` dictionary in configuration file.
