| Depending on inventory and desired config-id (configuration) the resize could either | ||
| require a reboot to complete, or be performed entirely live. The intention of this | ||
| command is to provide the user with a sane expectation ahead of making the resize | ||
| request. | ||
| If there is no inventory available, an exception will be raised. | ||
| Its important to note, this command will *not* make any changes to your Cloud Server. | ||
| This command is purely for information gathering. | ||
