> [vpc] new private gateway network is registered wrong in network table

> When creating a private gateway for a VPC router on a network not yet known
> to Cloudstack, Cloudstack ‘documents’ this network in the networks table.
> For normal guest networks, which should be associated with a single VPC,
> Cloudstack includes the VPC_ID in the database. The VPC_ID field is used to
> provision all networks and nics on a VPC router when it is created. Since
> this table is all about network provisioning it makes sense to ‘document’ the
> network cidr and gateway present in that nework. For guest tiers this usually
> is the VPC router itself, so the interface IP’s on a VPC router are the
> gateway IP’s found in the networks table.
> Unfortunately the VPC_ID is also recorded for the private gateway network
> when it is first created. So the first VPC to be plugged on the private
> gateway network also has that same network associated as a guest network
> tier, instead of just a private gateway network.
> This by itself will not quickly become a problem, because private gateways
> are first plugged on a running vpc router which is not likely to be recreated
> any time soon after that.
> But as soon as this first ever VPC router on the private gateway network is
> recreated due to a destroy of the VPC Router, all associated networks are
> looked up in the networks table.
> Because the private gateway network is ‘documented’ with the actual upstream
> gateway used by the VPC router defintion, the VPC router provisions a NIC on
> the private gateway network using the IP address of the actual upstream
> gateway creating an IP conflict on the private gateway network, effectively
> breaking down the upstream gateway functionality for all attached private
> gateways of other vpc's.
