Is there any way to perform the following operations from the dashboard (Horizon)?
nova interface-detach demo-intance1 demo-net-port-id
nova interface-attach --net-id demo-net2-id demo-instance1
I could not find anything but I thought something essential like this has to work somehow. The scenario is that I want to move an instance from one network to another.
Schema bellow is addressing your question, but works only via CLI ( I guess so )
