Hi, guys, I have two confused part in Ironic. (1) if I use nova boot api to launch an physical instance, how does nova boot command differentiate whether VM or physical node provision? From this article, nova bare metal use "PlacementFilter" instead of FilterScheduler.so does Ironic use the same method? ( http://www.mirantis.com/blog/baremetal-provisioning-multi-tenancy-placement-control-isolation/ ) (2)does Ironic only support Flat network? If not, how does Ironic implement tenant isolation in virtual network? say,if one tenant has two vritual network namespace,how does the created bare metal node instance send the dhcp request to the right namespace?
