I also tried the devices like this, but still getting the same error message
passthrough_whitelist = [... {"devname": "ens2f0", "physical_network": "sriovtenant1"}, {"devname": "ens2f1", "physical_network": "sriovtenant1"}]
thank you

Dear Openstack community,
I am facing an issue trying to setup neutron with SR-IOV and would like to ask for some help: openstack server show fault.
My environment is Openstack Rocky deployed with kolla-ansible.
I have edited the configuration files as suggested by the documentation but for some reason nova can't find the PCI device for pass-through.
This is my setup

Note: documentation says to use vlan but I am using flat networks
Why is nova looking for a device that libvirt doesn't know about?
