The interface defined in globals.xml is called br-mgmt, which is defined, on the hosts, as:
enp1s0f1 -\
---> bond0 ---> bond0.210 ---> br-mgmt
enp3s0 -/
br-mgmt being a bridged interface from bond0.210 vlan interface for bond0, which is in turn a bonding interface for eth0 and eth1, if I'm expressing myself correctly.
br-mgmt has an IP interface that is reachable from the lan, so properly configured. If, for testing purposes, I set network_interface to bond0 (which also has an IP address), prechecks work correctly. But when I set br-mgmt as designed, prechecks fails at the first check:
TASK [prechecks : Checking free port for Aodh API] *****************************
fatal: [openstack1]: FAILED! => {"failed": true, "msg": "ERROR! 'dict object' has no attribute u'ansible_br-mgmt'"}

Any idea why prechecks would fail in such an environment ?
FOund out the issue, though I'd like to understant why. That's the "-" in the middle of the interface name that breaks prechecks. If I remove it, or change it to "_", then prechecks work, strangely enough...
