[Openstack] [TripleO]: Deploying overcloud, undercloud as a VM fails

Hello,
I am trying to install the undercloud and basic overcloud as VM’s. My undercloud VM is installed and I am able to login to that fine.
I was following the instructions in http://docs.openstack.org/developer/tripleo-docs/basic_deployment/basic_deployment_cli.html to deploy the overcloud. In order to build the images, I need to apply some manual patches like the ones in https://bugzilla.redhat.com/show_bug.cgi?id=1304395 and after that the images are built. The BM introspection also went fine.
For both the controller and compute I get the error.
 “No valid host found.  There are not enough hosts available. Error 500”.

I deployed the overcloud using the “—libvirt-type qemu” option. Isn’t this good enough to deploy the overcloud as a VM? Do I also need to modify the flavors? I am not sure if the overcloud deploy is taking the VM option.The ironic node-show displays:

Any help on this will be very useful.

Thanks,
KP
