Unconfigured state in case of checking infra state during VMs creation

In case of using the IM in the HA mode. If the infrastructure creation call is made synchronously, and before returning the ID, the status of this infrastructure is gotten, an unconfigured state may raise because the HAProxy does not yet have the Inf ID in the sticky table, so the request may be redirected to another server (that has not the contextualization control of this infra) and may fail. It has no solution, it is mitigated using the asynchronous infrastructure creation to minimize the time until the Inf ID is returned and processed by the HAProxy.
