I'm not sure to have understood the question. The program executed are the same, the only difference is in the engine-setup plugins called that performs additional initialization for the data domain and those plugins are in the all-in-one subpackage of ovirt-engine-setup. The only difference I'm aware of in calling ovirt-host-deploy is that on AIO the automatic configuration of the firewall is disabled because it's already done by the setup.

I mean:
when you have separate engine + hosts you asynchronously deploy engine with engine-setup and this command doesn't care at all about host deploy. Then when you are comfortable, you add a host from the engine gui and here some program, call it PROGRAM_A I think is called from engine server itself towards the designated host
When a engine + separate host is deployed, engine scp ovirt-host-deploy there and perform the full host deployment running ovirt-host-deploy. This includes iptables configuration for vdsm if requested.
when you deploy AIO, the host part is automatically embedded at the end of engine setup phase and I presume PROGRAM_B is called from the engine itself towards itself as it is the designated host to deploy
When a engine is deployed AIO, engine-setup takes care of configuring iptables for BOTH the engine and vdsm and then engine run ovirt-host-deploy on the system _without_ configuring iptables. engine-setup then takes care of creating the data domain and attach it to the datacenter. So PROGRAM_A and PROGRAM_B are the same program, just run with different configuration.
If what I wrote above is correct which is the relation between PROGRAM_A and PROGRAM_B? Are they the same? If not, is there the chance that PRGRAM_B has not aligned to deploy CentOS 7.1 hosts, while PROGRAM_A has been aligned? Hope to have vlarified my point and doubts about possible problems.
