Hi, I am testing oVirt 4.2, I am using nested KVM for that. I am using two hypervisors Centos 7 updated and the hosted-Engine deployment using the ovirt appliance. For storage I am using iscsi and NFS4 Versions I am using : ovirt-engine-appliance-4.2-20180214.1.el7.centos.noarch ovirt-hosted-engine-setup-2.2.9-1.el7.centos.noarch kernel-3.10.0-693.21.1.el7.x86_64 I have a problem deploying the hosted-engine VM, when configuring the deployment (hosted-engine --deploy), it asks for the engine's hostname then the engine's IP address, I use static IP, in my lab I used *192.168.1.104* as IP for the VM engine, and I choose to add the it's hostname entry to the hypervisors's /etc/hosts But the deployment get stuck every time in the same place : *TASK [Wait for the host to become non operational]* After some time, it gave up and the deployment fails. I don't know the reason for now, but I have seen this behavior in */etc/hosts *of the hypervisor. In the beginning of the deployment the entry *192.168.2.104 engine01.example.local* is added, then sometime after that it's deleted, then a new entry is added with this IP *192.168.122.65 engine01.wodel.wd* which has nothing to do with the network I am using. Here is the error I am seeing in the deployment log 2018-03-24 11:51:31,398+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:100 TASK [Wait for the host to become non operational] 2018-03-24 12:02:07,284+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 {u'_ansible _parsed': True, u'_ansible_no_log': False, u'changed': False, u'attempts': 150, u'invocation': {u'module_args': {u'pattern': u'name=hyperv01.wodel.wd', u'fetch_nested': False, u'nested_attributes': []}}, u'ansible_facts': {u'ovirt_hosts': []}} 2018-03-24 12:02:07,385+0100 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:98 fatal: [loc alhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": []}, "attempts": 150, "changed": false} 2018-03-24 12:02:07,587+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 PLAY RECAP [engine01.wodel.wd] : ok: 15 changed: 8 unreachable: 0 skipped: 4 failed: 0 2018-03-24 12:02:07,688+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:94 PLAY RECAP [localhost] : ok: 41 changed: 14 unreachable: 0 skipped: 3 failed: 1 2018-03-24 12:02:07,789+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:180 ansible-playbook rc: 2 2018-03-24 12:02:07,790+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:187 ansible-playbook stdou t: 2018-03-24 12:02:07,791+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:189 to retry, use: --limi t @/usr/share/ovirt-hosted-engine-setup/ansible/bootstrap_local_vm.retry 2018-03-24 12:02:07,791+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils.run:190 ansible-playbook stder r: 2018-03-24 12:02:07,792+0100 DEBUG otopi.context context._executeMethod:143 method exception Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/otopi/context.py", line 133, in _executeMethod method['method']() File "/usr/share/ovirt-hosted-engine-setup/scripts/../plugins/gr-he-ansiblesetup/core/misc.py", line 186, in _closeup r = ah.run() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/ansible_utils.py", line 194, in run raise RuntimeError(_('Failed executing ansible-playbook')) RuntimeError: Failed executing ansible-playbook 2018-03-24 12:02:07,795+0100 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Closing up': Failed exec uting ansible-playbook any idea????
