This sounds like the nodes either weren't introspected properly, have
incorrect boot settings, or do not meet the criteria for your flavors.

In particular, did you possibly forget to run "openstack baremetal
configure boot"? This has to be run after you import the nodes from
instack_env.json, and it will assign the kernel and ramdisk to the nodes.

The instructions for this process begin here:
http://docs.openstack.org/developer/tripleo-docs/basic_deployment/basic_deployment_cli.html#introspect-nodes

You want to make sure that when you run "openstack baremetal
introspection bulk start" that the introspection completes
successfully. You can then use "ironic node-list" and "ironic node-show
<UUID>" to see the basic info about the host. The default baremetal
flavor requires 4G of RAM and 40G of hard drive space. Do your nodes
meet that minimum criteria? That's another cause of the "not enough
hosts available", although I think the configure boot setting is a more
likely culprit.

If you are trying to assign nodes to roles (Controller, Compute, etc.),
then you will want to review this section:
