ECS Statuses¶
An ECS can be in one of the following statuses specified in ECS APIs:
status: specifies an ECS status, which is generated by OS-EXT-STS:vm_state and OS-EXT-STS:task_state.
OS-EXT-STS:vm_state: indicates that the ECS is in a stable state after an operation is performed. This is an extended attribute.
OS-EXT-STS:task_state: indicates an intermediate status in which the ECS is processing an operation performed on it. This is an extended attribute.
