@andersonalipio I would be interested to get some elements from your installation.
your /var/log/sdn-controller-plugin.log file (on the host) in order to check the parameter passed by XO.
output of xe network-param-list uuid=$UUID (for the network concerned) or xe network-list params=all (if uuid is unknown)
output of xe pool-list params=other-config (for xo:sdn-controller:* elements)
output of xe vif-list params=uuid,network-uuid,other-config (for xo:sdn-controller:* elements)
Feel free to share it privately via PM if you prefer, possibly using https://paste.vates.tech/ .
Cc @Team-XO-Backend too (as it could be from XO side)
