Hello!

Using this command line :
hammer --username admin --password nms123 host create --hostgroup-id 2 --compute-resource-id 11 --name newnode --interface="type=interface,primary=true,provision=true,managed=true,virtualnic=false" --compute-attributes "flavor_ref=2,tenant_id=5c231dcefbce40c0b57b6f2db60b8b71,security_groups=default,image_ref=7dd9edd9-b70b-4663-b651-e88f250053ef,net_id=private_admin"

I got error message :

Using compute resource GUI it works fine.
I'm new to foreman, maybe I miss something in my command line. But at least I would not expect such error message.
