Host machine not being discovered by RHEL OpenStackInstaller

Hi,
I have installed RHEL 7.1 OpenStack Platform (TRIAL VERSION) in my machine. After this I have logged in to Red Hat OpenStack Installer webpage. Now I am trying to add another machine as "discovered host" through PXE booting. During PXE boot, DHCP lookup is successful and after this it shows "FOREMAN DISCOVERY" on screen .
But after this we are getting some errors during PXE booting of the host. Also in RedHat OpenStack Installer webpage, no machines are discovered in "Discovered Hosts" under "Hosts" tab.
Both these machines(OpenStack Installer and Host) are on same subnet.

Error snapshot on host machine has been attached.
1. systemd-readhead error
2. Could not send facts to foreman - Connection refused error

Please help!
