[ovirt-users] can not deploy local host

Hello, guys. Could not create a new host from virtualization manager. Mine is a fresh centos 7 server , I followed the video tutorial " oVirt Open Virtualization Basics -- Single Machine Install" Result: Ovirt engine is up , I can connect to the engine but when creating the local host it returns "Failed to install Host local. Failed to execute stage 'Closing up': Command '/bin/systemctl' failed to execute" I have been looking in the las file generated at /var/log/ovirt-engine/host-deploy, but can not found more information, just the same line. Where can I read a little more to solve it ? Regards, Leandro.
