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"
