Hi all -
I'm not sure how people found these melange policy create commands -
is there a doc plan for Melange commands such as those described here?
I read through the API doc housed on github but wasn't sure how CLI
commands are handled.
Thanks in advance for some clarity,
Anne

The default melange policy allows assignment of the network address and
synthesise a gateway address (if it is not specified). It will not hand
out the gateway address. The "fix" is to create an ip policy that
restricts the octect 0. I think the syntax is something like
`melange policy create -t {tennant} name={block_name}
desc={policy_name}` (This should return the policy_id for the next
command)
`melange unusable_ip_octet create -t {tennant} policy_id={policy_id}
octect=0`
`melange ip_block update -t {tennant} id={block_id}
policy_id={policy_id}`

You need to create your networks through nova-manage, otherwise the nova
tables don't get filled in. The next release we are axing the nova
tables as it was just a crutch to get it "usable".
Happy Hacking!
