Hi Zhenguo (and others),

is there a description/email thread/documentation about how mogan and nova co-exists in the same cloud? In particular, will it be possible for mogan and nova (with ironic driver) to run? Is this something that we will recommend or not recommend or not mention? Because I don't see how the end user will know to issue a mogan command to get a baremetal server, vs a nova-boot command to get a baremetal server. And/or does anyone envison that horizon will hide all that from the user somehow?

As I understand, baremetal instance in nova is a 'specical virtual machine'(raw performance). Users claim the instance by specifying a flavor with 'vcpus', 'memory', "root_gb" instead of real hardware specs like (cpu model/cores, hard drives type/amount, nics type/amount), then he get an instance with properties like 'vm_state' and other 'virtual' stuff. As baremetal in nova use the same model and same set of API that designed for vms, so even for end users, it's not that easy to know which instance is a baremetal server, so maybe it's good to call that baremetal server a special vm instance.

So, yes the end user actually know that there is a difference between getting a bremetal instance via mogan or via nova :)
