growing fixed-ip network

Hi,

I don't know how to handle the case when a tenant has used up all IPs.
We use FlatNetworking, so no Floating IPs possible.
So, when one tenant has used up all the IPs in their net, how can I assign another net
to the same tenant ? If I just assign another net, every new instance just gets an IP from both nets.
But if the first net doesn't have free IPs, I get the exception.NoMoreFixedIps()
even if the second net still has lots of IPs.

Can this be solved with quantum ?

Cheers,
Christoph

It should hop on to the next subnet block if available ( assuming that in
LAN its a private address scheme ) .

We only use routable IPs. thats why we have some nets which can't be subnetted.
What difference does it make if its private adress space ?

The major reason to use private address space is that there is likely
a lot more of it than you have in public address space. if you have
effectively unlimited fixed_ip space, you can give each project a lot.
For example, we give each project a /23. While a user could
potentially still run out of address space on our system, it hasn't
happened yet with our workload.

Also.. builds are better created in Private IP and then prepped to release
to Public cloud. After all just an instance rinning OS is not yet there in
terms of APP stack.

Since openstack doesn't do this, its just not possible to
grow grow the network ?

Re: growing fixed-ip network [In reply to]

clarify more. By growing network do you mean adding more machine machines
instances ?

More instances. The tenant has used up the first net, has 254 instances running and now wants to add
more instances. But since the net is full, it has to be another net. But this does not work.
