| Generic system models |
| ===================== |
| |
| This repo contains general reclass system level of salt model. It is to be |
| used along with service models and concrete cluster deployment model. |
| |
| Network configuration |
| ===================== |
| |
| Enable SR-IOV support |
| --------------------- |
| |
| Include class at `cluster.<name>.openstack.compute` |
| |
| .. code-block:: yaml |
| |
| - system.nova.compute.nfv.sriov |
| |
| For single SR-IOV interface setup you can set parameters: |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| `sriov_nic01_device_name` |
| Name of the Physical Function interface (pF) |
| |
| `sriov_nic01_numvfs` |
| Number of Virtual Functions (VF), for number of |
| supported VF check documentation for your network interface card. |
| |
| `sriov_nic01_physical_network` |
| Default **physnet1**, label for physical network the interface belongs to. |
| |
| `sriov_unsafe_interrupts` |
| Default **False**, needs to be set **True** if your hw platform does not |
| support interrupt remapping. |
| |
| |
| Multiple SR-IOV interface setup: |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| By default, the metadata model contains configuration for 1 NIC |
| dedicated for SR-IOV, so we need to setup network interfaces like in the |
| following example. |
| |
| .. code-block:: yaml |
| |
