On deploying Pike bundle I got the error below.
ERROR cannot deploy bundle: cannot deploy application "nova-cloud-controller": option "ram-allocation-ratio" expected float, got 64
The same problem applies to cpu-allocation-ratio option.
The value of both options should be given in canonical floating number format.
ram-allocation-ratio: 64.
cpu-allocation-ratio: 64.
