| Petr Jediný | efc605a | 2017-03-27 11:49:40 +0200 | [diff] [blame^] | 21 | For single SR-IOV interface setup you can set parameters: |
| 22 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 23 | |
| 24 | `sriov_nic01_device_name` |
| 25 | Name of the Physical Function interface (pF) |
| 26 | |
| 27 | `sriov_nic01_numvfs` |
| 28 | Number of Virtual Functions (VF), for number of |
| 29 | supported VF check documentation for your network interface card. |
| 30 | |
| 31 | `sriov_nic01_physical_network` |
| 32 | Default **physnet1**, label for physical network the interface belongs to. |
| 33 | |
| 34 | `sriov_unsafe_interrupts` |
| 35 | Default **False**, needs to be set **True** if your hw platform does not |
| 36 | support interrupt remapping. |
| 37 | |
| 38 | |
| 39 | Multiple SR-IOV interface setup: |
| 40 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| 41 | |
| 42 | By default, the metadata model contains configuration for 1 NIC |
| 43 | dedicated for SR-IOV, so we need to setup network interfaces like in the |
| 44 | following example. |
