Good day,

Encountered such a problem when migrating to ovirt 4.4
At
hosted-engine --deploy --restore-from-file=backup.bck

Getting, error below

Upgrading engine extension configuration: /etc/ovirt-engine/extensions.d/xx-xxxx.properties", "[ INFO  ] Upgrading CA", "[ INFO  ]
Creating CA: /etc/pki/ovirt-engine/qemu-ca.pem", "[ ERROR ] Failed to execute stage 'Misc configuration': [Errno 17]
File exists: '/etc/pki/ovirt-engine/ca.pem' -> '/etc/pki/ovirt-engine/apache-ca.pem'", "[ INFO  ]
DNF Performing DNF transaction rollback", "[ INFO  ] Stage: Clean up",

At setting of initial parameters I select "No" parameter in para

'Renew engine CA on restore if needed? Please notice ' 'that if you choose Yes, all hosts will have to be ' 'later manually reinstalled from the engine. ' '(@VALUES@)[@DEFAULT@]

Dosnt need to renew the .ca certificate, thats upgrade and dosnt need to re-make connections with nodes!

Even with this item, he still tries to create a new certificate.
