Testing OVN with SRIOV with latest wallaby. I have following configuration for SRIOV.
# created network (my gateway is my datacenter physical router)
neutron subnet-create net_vlan69 10.69.0.0/21 --name sub_vlan69 --allocation-pool start=10.69.7.1,end=10.69.7.254 --dns-nameservers 10.64.0.10 10.64.0.11 --gateway=10.69.0.1
# ml2_config.ini
mechanism_drivers = ovn,sriovnicswitch
# sriov_nic_agent.ini
[agent]
[securitygroup]
firewall_driver = neutron.agent.firewall.NoopFirewallDriver
[sriov_nic]
exclude_devices =
physical_device_mappings = vlan:eno49,vlan:eno50
# compute / nova.conf
[pci]
# White list of PCI devices available to VMs.
passthrough_whitelist = { "physical_network":"vlan", "devname":"eno49" }
I have created neutron port and then try to create instance using it i got following error in neutron-server.log
