1. It appears that ovnkube-trace file is looking for an annotation " k8s.ovn.org/node-mgmt-port-mac-addresses" in map[string]string format with default network and fails to execute, but in the default installation, there is already an annotation in the node " k8s.ovn.org/node-mgmt-port-mac-address". 

F0816 01:50:26.953094 1538153 ovnkube-trace.go:1282] Failed to get information from pod ovnkube-node-5vfz6: macAddress annotation not found for node sptl4ocpsno02.telecom.tcnz.net; error: could not find "k8s.ovn.org/node-mgmt-port-mac-addresses" annotation

What ovnkube-trace tool expects: 
k8s.ovn.org/node-mgmt-port-mac-addresses: '{"default": "7a:87:e4:f1:50:7e"}' 

What's present on the node: 
k8s.ovn.org/node-mgmt-port-mac-address: '{"7a:87:e4:f1:50:7e"}'

2.  ovnkube-trace file inside the ovnkube-node, is built with cgo enabled.
