Subject Re: How can I allocate a specific IP when I create an instance.
Date Wed, 26 Jun 2013 16:18:58 GMT
Its feasible to do this, you can pick a host to deploy to (as an admin) so
you know what pod it will eventually land in and its ip address space. I
say file an enhancement, bring it up to dev and have it discussed and voted
upon.
