Unable to add host to Redhat Virtualization manager

Hello,
I have installed Redhat 7 on bare metal and installed Redhat Virtualization manager 4.2. When I try to add the host it always fails with this error:

2018-09-26 16:57:57,320+05 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [7bd3867e-1cb3-4793-9639-284106dfe9e1] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host Redhat: Failed to execute stage 'Setup validation': Cannot locate ovirt-host package, possible cause is incorrect channels.
