spec.running in body is required

If I add to running: false to the spec section, it works then.

Running has always been marked as a required field in our API. The only difference now is required fields are being enforced at creation time.

All our example ovms reflect this requirement.

[petrkotas]

The running is required field and have to be provided. If you do not add running:true|false than the ovm does not have any information how to proceed. We can discuss whether the ovm should do some defaulting to set default value to be running: false. @rmohr @fabiand what do you think?

[fabiand]

I'd say we can sanely default to running: false - it would just be a default like with any other field.

Defaulting running to "false" makes sense when the object is called a OfflineVirtualMachine. What about when we change the name to something like a StatefulVirtualMachine? I'd be confused if I posted a SVM and it didn't run.

The name OVM will change soon. I'd suggest leaving running as a required field until then. After we settle on a name, we can decide what the default should be for running.

[petrkotas]

I tend to agree with David. running: false for statefull VM is confusing. Having it required means, user have to decide what he wants to do with it.

I agree the different names may be confusing. I don't agree with putting a burden of the user to have to decide as a simple way out for us (as a general rule of thinking, sometimes we have to)

yep, I agree. We need a default. I suggest we hold off on making a decision about the default until after we are 100% committed to a name (ovm vs svm discussion) because the name impacts the default we use.
