Sorry, I think you have to either remove "OvercloudControlFlavor: control" or 
tweak you flavors (the former is the easiest). 
 Backup e-mail has been used due to local DNS issues with
hotmail.com.
 Follow 
http://tripleo.org/advanced_deployment/baremetal_overcloud.html
 with  your sample
 parameter_defaults:
      IronicEnabledDrivers:
          - pxe_ssh
          - pxe_ipmitool
      IronicCleaningDiskErase: 'metadata'
      ControllerCount: 1
      ComputeCount: 0
      OvercloudControlFlavor: control
      NtpServer: 'pool.ntp.org'
 via instack-virt-setup with
 NODE_CPU=2
 NODE_COUNT=2
 NODE_MEMORY=80000
 UNDERCLOUD_MEMORY=12000
 on  32 GB VIRTHOST 4 CORE i7 CPU (Haswell )
 Every time get during overcloud deployment

 2016-10-10 07:35:42Z [overcloud.Controller.0.Controller]: CREATE_FAILED
 ResourceInError: resources.Controller: Went to status ERROR due to "Message: No
 valid host was found. There are not enough hosts available., Code: 500"
==================================================================================================
 Due to limited experience both cases tested
 1. openstack baremetal introspection bulk start -  is skipped <== I guess has to
 be skipped.
 2. openstack baremetal introspection bulk start -   is done
 Before overcloud-deploy.sh run.
 Crashes with same error above.
 Repos setup (same on VIRTHOST and "instack VM") :-
 $ sudo yum -y install yum-plugin-priorities
 $ sudo curl -o /etc/yum.repos.d/delorean-newton.repo \
    
http://buildlogs.centos.org/centos/7/cloud/x86_64/rdo-trunk-newton-tested...
 $ sudo curl -o /etc/yum.repos.d/delorean-deps-newton.repo \
    
https://trunk.rdoproject.org/centos7-newton/delorean-deps.repo
 One other test has been completed OK .
