Our orchestration queue has a mechanism to prevent multiple DHCP orchestration calls. It uses MAC address to identify duplicates however for NIC alias there are actually two NICs with same MAC address. Adding an extra information to the orchestration name allows orchestrating those.

Reproducer is simple, create a subnet with Internal DB IPAM, static mode (id=3 in my case) and a subnet with DHCP IPAM, static mode (id=9 in my case) and create a host with an alias as provisioning interface. It must have name associated too:

hammer -u admin -p changeme host create --name simple-13006 --organization MyOrg --location MyLoc --hostgroup 'CentOS 7.1' --interface identifier=eth0,mac=52:54:00:45:ae:90,primary=true,provision=false,domain_id=1,subnet_id=3 --interface identifier=eth0:1,mac=52:54:00:45:ae:90,primary=false,provision=true,domain_id=1,subnet_id=9,virtual=true,attached_to=eth0,name=prov-32042
