Open Stack

Hi Kial,

Hold on...
You obviously didn't understand my question. So please don't try to
teach me anything. I can admit that the initial description of my
request was a bit unclear. So I'm gonna try to clarify it.

I use nova-network with the VLAN manager, so I have a network range
per projects (fixed ips), per VLAN. Each project uses a specific pool,
I use the floating IPs to expose instances to another private network
and I don't use the "auto_assign_floating_ip" parameter.

Now, when I perform a "nova floating-ip-create <my-pool>" this gives
me the first floating IP available of that pool. What I want to
know/achieve is to decide the floating IP address to create. Basically
this could lead to a command like:

# nova floating-ip-create <my-pool> <floating-ip-that-I-want-create-from-a-pool>

But as you can see below, it's not available from the CLI:

# nova help floating-ip-create
usage: nova floating-ip-create [<floating-ip-pool>]

Allocate a floating IP for the current tenant.

Positional arguments:
  <floating-ip-pool>  Name of Floating IP Pool. (Optional)

Then I'll associate this floating IP to one of my instances.

Let's try to raise the level of this discussion. Now if there is
something that I don't know, or something that I missed, feel free to
teach/correct me. I'm looking for a workaround, or code patch.
Something that doesn't require huge amount of work. Is that doable?

Anyone?
