Hi, I have launched the an instance through horizon and it went to ERROR state, due to No valid host was found : Insufficient Resources : No enough hosts available.

When the instances is not able to launch, the instance statue is changed to ERROR state and the tables actions are visible. In the tables actions, I can see that you can associate or dis-associate a floating IP to the ERROR state instance.

What is the use case of keep those two actions association and disassociation of floating IP to the instance in ERROR state ?

Depends on the error state. Did you take a look at /var/log/nova/* or /var/log/horizo/horion.log.

Even though a machine may have an error state, it might still have a working interface to plumb an ip too.

At a guess, if its a kernel panic or something of a total failure, then you could look to raise it as a bug.

Hi Luke, As my current error state is because of "Insufficient resources like I don't have RAM and vCPU" Do you mean to say that if an Instance is failed because of some internal errors, at that time we can attach a floating IP and debug/work on it ?

IMHO , as an error instance cannot be re-launched, it is not worth to assign a IP. Though other current action such edit instance , lock / unlock might be helpful.
