That sounds essentially correct.  Note that all 15 vms aren't used in a
normal devtest run, but we create them all anyway because of some
difficulties adding new environments in some situations (namely CI, I
believe).

I guess what it means is as below:  - 1 Seed VM as deployment starting point.  - Both undercloud and overcloud images are loaded into Glance of Seed VM.  - 15 VMs are created. 1 for undercloud, 1 for overcloud controller, left 13 are for overcloud compute.  - 1 Host machine acts as container for all 15 VMs. It can be separated from Seed VM.  - Seed VM communicates with Host machine to create 15 VMs and installed corresponding images.  Is it correct? Or can you roughly introduces the topology of the devtest virtual environment.
