[Openstack] Wading through nova.conf options

Hi Anne,

Thanks for the link!  That is very close to what I was looking for.

Is there an easy way to tell what the valid options are for a given
configuration option?  For example:

# Driver to use for network creation (string value)
#network_driver=nova.network.linux_net

Is there way to find the list of valid options for parameters like this?

Some options such as network_api_class are covered in the provided
documentation, but a large number of them are not.


Thanks for the links!

Sam
