[ovirt-users] migrating to Hosted Engine failed

Hello, *oVirt Node: 4.2.7.1* I'm trying to migrate to a hosted engine on an existing cluster. I following: https://www.ovirt.org/documentation/self-hosted/chap-Migrating_from_Bare_... or: https://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-en... <https://www.ovirt.org/develop/developer-guide/engine/migrate-to-hosted-en... in both cases, it waits for the guest to be up until falling with an error I can see that it added some record to /etc/host and the guest is up. I was able to connect to the guest with ssh from the host that runs the hosted-engine deployment. after many retries, the host removes the guest and throw the error. also now the host cannot be activated back and throw following error when tring to activate: [ ERROR ] fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_hosts": [{"address": "kvm7.replaceddomain.com", "affinity_labels": [], "auto_numa_status": "unknown", "certificate": {"organization": " replaceddomain.com", "subject": "O=replaceddomain.com,CN= kvm7.replaceddomain.com"}, "cluster": {"href": "/ovirt-engine/api/clusters/49af9e16-1250-11e9-ba8c-00163e4e185e", "id": "49af9e16-1250-11e9-ba8c-00163e4e185e"}, "comment": "", "cpu": {"speed": 0.0, "topology": {}}, "device_passthrough": {"enabled": false}, "devices": [], "external_network_provider_configurations": [], "external_status": "ok", "hardware_information": {"supported_rng_sources": []}, "hooks": [], "href": "/ovirt-engine/api/hosts/18517a0d-f264-4fd7-a191-c4a1f035da94", "id": "18517a0d-f264-4fd7-a191-c4a1f035da94", "katello_errata": [], "kdump_status": "unknown", "ksm": {"enabled": false}, "max_scheduling_memory": 0, "memory": 0, "name": "kvm7.replaceddomain.com", "network_attachments": [], "nics": [], "numa_nodes": [], "numa_supported": false, "os": {"custom_kernel_cmdline": ""}, "permissions": [], "port": 54321, "power_management": {"automatic_pm_enabled": true, "enabled": false, "kdump_detection": true, "pm_proxies": []}, "protocol": "stomp", "se_linux": {}, "spm": {"priority": 5, "status": "none"}, "ssh": {"fingerprint": "SHA256:FL4Drh9DQxHFwyQQ9LXEyNjex62LBZ6c4+4O09LoTWg", "port": 22}, "statistics": [], "status": "install_failed", "storage_connection_extensions": [], "summary": {"total": 0}, "tags": [], "transparent_huge_pages": {"enabled": false}, "type": "ovirt_node", "unmanaged_networks": [], "update_available": false}]}, "attempts": 120, "changed": false, "deprecations": [{"msg": "The 'ovirt_hosts_facts' module is being renamed 'ovirt_host_facts'", "version": 2.8}]} [ INFO ] TASK [Fetch logs from the engine VM]
