[Bug 1372441] Re: Creating port in dual-stack network requires IPv4 and IPv6 addresses to be allocated

 

I don't think I can agree with this.

The allocation of a dual-stack network for a  guest is not best-effort:
the user has a specific intention and the platform should honor it. If
it is unable to do so, it should fail.

Title:
  Creating port in dual-stack network requires IPv4 and IPv6 addresses
  to be allocated

Status in OpenStack Neutron (virtual network service):
  Opinion

Bug description:
  Currently, when creating port in dual-stack network (network with one
  ore more IPv4 subnets and one or more IPv6 subnets), Neutron allocates
  fixed-ip from both, v4 and v6 subnets.  If one of the subnets do not
  have available addresses, it is considered as error.

  IMO, this is wrong.  Operation should succeed if at least one address
  (IPv4 of IPv6) was allocated.
