Re: [Openstack] growing fixed-ip network
clarify more. By growing network do you mean adding more machine machines 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.

Re: [Openstack] growing fixed-ip network
It should hop on to the next subnet block if available ( assuming that in LAN its a private address scheme ) .

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. -nld ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] growing fixed-ip network
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. Ravi.
