There was a desire to conduct a test backup and restore operation ovirt-node-ng 4.3.2-2019031908 Operations performed: - Deployed two test hosts, configured Hosted Engine. Created two test VMs. - Created a backup copy # engine-backup --mode=backup --file=ovirt-full-backup_2023-09-04.tar --log=ovirt-full-backup_2023-09-04.log - Turned off the original Self-hosted Engine and disconnected from Self-hosted Domain Storage # hosted-engine --vm-shutdown # hosted-engine --disconnect-storage - Created a new host using a previously created backup # hosted-engine --deploy --restore-from-file=ovirt-full-backup_2023-09-04.tar Although an error occurred at the end of the installation (after the start of copying to the iSCSI shared storage), but oVirt is accessible via the Web. The error that occurred [ INFO ] TASK [ovirt.hosted_engine_setup : Check for the local bootstrap VM] [ ERROR ] Error: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook ... [ INFO ] Stage: Clean up [ INFO ] Cleaning temporary resources [ ERROR ] Hosted Engine deployment failed: please check the logs for the issue, fix accordingly or re-deploy from scratch. Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20230907201859-ovmmky.log In the Web interface - all Hosts are green - all VMs are green. There is a virtual machine "external-HostedEngineLocal". - Storage Domain "hosted_storage_old_20230907T202958" is present. Any questions: 1. The instructions say that at the end you need to reinstall the hosts. Is it necessary to do this? I ask, because in my case, all hosts are available to the manager, virtual machines are working. What is this operation necessary for? 2. What to do with the "external-HostedEngineLocal" virtual machine? 3. Why the "Error" error occurred: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"? Can it be related to the lack of access to the Internet (repository) have a VM Engine? When installing hosts, access to the Internet is required (otherwise the installation does not occur), I register access through a proxy in yum.conf
