I have read in the ECA course some recommandation from Nutanix regarding AHV Networking specialy for LACP.
If this is a best practice please Nutanix do as usual and set it by default :
"ovs-vsctl set port br0-up other_config:lacp-fallback- ab=true”
"ovs-vsctl set port br0-up other_config:lacp-time=fast"
