OVS-DPDK uses OVS network with DPDK drivers. SRIOV enables network traffic to bypass the software switch layer of the Hyper-V stack. +Emulated machine type +^^^^^^^^^^^^^^^^^^^^^ + +For better performance test results of emulated VM spawned by Yardstick SA +context (OvS-DPDK/SRIOV), it may be important to control the emulated machine +type used by QEMU emulator. This attribute can be configured via TC definition +in ``contexts`` section under ``extra_specs`` configuration. + +For example: + +.. code-block:: yaml + + contexts: + ... + - type: StandaloneSriov + ... + flavor: + ... + extra_specs: + ... + machine_type: pc-i440fx-bionic + +Where, ``machine_type`` can be set to one of the emulated machine type +supported by QEMU running on SUT platform. To get full list of supported +emulated machine types, the following command can be used on the target SUT +host. + +.. code-block:: yaml + + # qemu-system-x86_64 -machine ? + +By default, the ``machine_type`` option is set to ``pc-i440fx-xenial`` which is +suitable for running Ubuntu 16.04 VM image. So, if this type is not supported +by the target platform or another VM image is used for stand alone (SA) context +VM (e.g.: ``bionic`` image for Ubuntu 18.04), this configuration should be +changed accordingly. + Standalone with OVS-DPDK ^^^^^^^^^^^^^^^^^^^^^^^^ |
