So this might be simple, but my forehead is sufficiently bruised that similar bruises to my ego are acceptable.
I have a vCloud deployment which is relatively simple with direct external networks for each org vDC. When I run the out of the box "instantiate a vapp template" workflow from vCO the vapp is instantiated with no vApp or VM networks. This is easily correctable via the vCD WebUI, but I've yet to hit on a vCO method to correct this.
The "Wire a virtual machine network" workflow doesn't work because the vApp has no networks. "Add a vApp network" wants to create a new network rather than "add" an existing network to the vApp. The publicly available PSO scripts appear to do the same.
I've spent some time trying to code my own but am not at all clear what the process is to update the vApp with an existing network that I can then turn around and "connect" the vms to. I've trolled all over the vCO API browser but haven't found much in the way of enlightenment so far though I've managed to become very confused on the relation between networkconfig and networkconnection, if any...
It might very well be that I'm approaching things all wrong. Any pointers would be greatly appreciated, particularly in the area of "reconfiguring" network settings to connect to existing networks via vCO.
