While working on a conversion of a node to support SRIOV, I removed ovn-chassis from the machine and added a new app ovn-chassis-sriov with this configuration:
ovn-chassis-sriov:
charm: cs:ovn-chassis-10
options:
bridge-interface-mappings: br-data:bond0
enable-hardware-offload: false
enable-sriov: true
ovn-bridge-mappings: physnet1:br-data sriovfabric1:br-data sriovfabric2:br-data
sriov-device-mappings: sriovfabric1:enp129s0f0 sriovfabric2:enp129s0f1
sriov-numvfs: enp129s0f0:32 enp129s0f1:32
But sriov port creation was failing with error:
2021-04-13 12:54:02.468 8249 ERROR nova.compute.manager [instance: 3c029b35-8e28-46de-88fd-7b5b8ef0dedd] libvirt.libvirtError: Cannot set interface MAC/vlanid to fa:16:3e:67:8b:0d/3060 for ifname enp129s0f0 vf 31: Operation not supported
We found that the issue was with having mlnx-switchdev-mode service enabled.
Once disabled it and rebooted the node, sriov worked.
Charm should disable this service if enable-sriov is true or enable-hardware-offload is false. |
