Here's a reproducer:
juju deploy ubuntu # onto a vm or metal, can't repro with lxd
juju ssh ubuntu/0 sudo apt-get install openvswitch-switch -y
juju ssh ubuntu/0 'sudo ovs-vsctl add-br br0; sudo ovs-vsctl add-port br0
dpdk-p0 -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:01:00.0'
Error output from the add-port command is:
ovs-vsctl: Error detected while setting up 'dpdk-p0': could not open network
device dpdk-p0 (Address family not supported by protocol). See ovs-vswitchd
log for details.
ovs-vsctl: The default log directory is "/var/log/openvswitch".
You can then query 'ovs-vsctl show' and see:
Bridge br0
Port dpdk-p0
Interface dpdk-p0
type: dpdk
options: {dpdk-devargs="0000:01:00.0"}
error: "could not open network device dpdk-p0 (Address family
not supported by protocol)"
Port br0
Interface br0
type: internal
ovs-vsctl -f csv list Interface | grep 'not supported'
provides a response that could also be alerted on as an active
configuration issue rather than alerting on presence of the log entry.
$ sudo ovs-vsctl -f csv list Interface |grep 'not supported'
