Hi Yuanle, thanks for this very useful information. I have tried to update the existing port and was getting Duplicated options --fixed-ip subnet_id=2d30ade0-5713-4857-b610-9ab29453ab92 --fixed-ip subnet_id=2d30ade0-5713-4857-b610-9ab29453ab92 But I was able to use port-create successfully. Is there a way to change a port ID of a running instance in nova? Since my instance is running and I don't want to terminate it and boot it again. Or can I use this --nic port_id parameter just when creating a new instance with nova boot ....?
