The CONF.compute.max_disk_devices_to_attach option controls the maximum number of disk devices allowed to attach to an instance. If it is set to 0, it will literally allow no disk device for instances, preventing them from being able to boot. This adds a note to the config option help to call this out and changes nova-compute to raise InvalidConfiguration during init_host if [compute]max_disk_devices_to_attach has been set to 0. The nova-compute service will fail to start if the option is set to 0. Note: there doesn't appear to be any way to disallow particular values in a oslo.config IntOpt other than the min/max values. Here we need the min value to be -1 to represent unlimited. There is a 'choices' kwarg available but that is only for enumerating valid values and we need to allow any integer >= 1 as well.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
