[ovirt-users] First host within Self-Hosted engine stays in non-responsive state

I am trying to setup self-hosted-engine (4.2) on a single machine running centos 7.4. I ran hosted-engine deploy script and it ran all the way through but failed on last task (at "Wait for the local bootstrap VM to be down at engine eyes") while creating the local engine VM. However, the --vm-status shows the engine status as up and is in good health, but I cannot interact with host installed on engine VM. The host within engine VM shows it is in non-responsive state, not clear why and what caused it. I can ssh into the local engine VM and the engine.log has below entries - 2018-05-17 11:03:57,739+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.VmDevicesMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-78) [6768004b] Exception:: org.springframework.dao.DataIntegrityViolationException: CallableStatementCallback; SQL [{call insertvmdevice(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)}]; ERROR: insert or update on table "vm_device" violates foreign key constraint "fk_vm_device_vm_static" Detail: Key (vm_id)=(114581bb-7fef-4b08-8e3c-85dd5a9e680b) is not present in table "vm_static". ... ... ... 2018-05-17 11:03:59,957+01 ERROR [org.ovirt.engine.core.bll.pm.FenceProxyLocator] (EE-ManagedThreadFactory-engineScheduled-Thread-44) [2bf8b18f] Can not run fence action on host 'ovirt', no suitable proxy host was found. ... ... ... 2018-05-17 11:20:00,093+01 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (EE-ManagedThreadFactory-engine-Thread-2) [1a833057] Exception during connection ... ... ... 2018-05-17 11:20:00,386+01 ERROR [org.ovirt.engine.core.vdsbroker.HostDevListByCapsVDSCommand] (EE-ManagedThreadFactory-engine-Thread-2) [1a833057] Command 'HostDevListByCapsVDSCommand(HostName = ovirt, VdsIdAndVdsVDSCommandParametersBase:{hostId='1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99', vds='Host[ovirt,1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99]'})' execution failed: java.net.UnknownHostException: ovirt: Name or service not known ... ... ... 2018-05-17 11:20:03,287+01 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Exception during connection 2018-05-17 11:20:03,292+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Unable to RefreshCapabilities: UnknownHostException: ovirt 2018-05-17 11:20:03,294+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Command 'org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand' return value 'org.ovirt.engine.core.vdsbroker.vdsbroker.VDSInfoReturn@46e3da89' 2018-05-17 11:20:03,294+01 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] HostName = ovirt 2018-05-17 11:20:03,297+01 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-14) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = ovirt, VdsIdAndVdsVDSCommandParametersBase:{hostId='1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99', vds='Host[ovirt,1a6a47e6-934e-43f7-ad5b-ba8f8ff8df99]'})' execution failed: java.net.UnknownHostException: ovirt 2018-05-17 11:20:03,316+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-15) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM ovirt command GetCapabilitiesAsyncVDS failed: Connection issue ovirt 2018-05-17 11:20:03,317+01 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-15) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: Connection issue ovirt ... ... ... and then above 5 ERROR messages are keep getting repeated. Why the connection fails when I can still ssh into the engine? where is the issue here?
