cache_mode missing in form

[purplesrl]

when creating a new instance from a flavor cache_mode is not inserted in the template.html, but it is required in create/forms.py

cache_mode = forms.CharField(error_messages={'required': _('Please select HDD cache mode')})

Since the form.is_valid() function will fail, nothing will be created, it will just silently exit.

To fix this under <input type="hidden" name="hdd_size" value="{{ flavor.disk }}"> in template.html add:

<input type="hidden" name="cache_mode" value="default"> To completely fix this, when the flavor is created cache mode should be added.
