During Full VM recovery, the virtual machine creation failed.

1. Duplicate VM name

2. Connection to oVirt engine failure

3. Authentication failure of oVirt Engine console credentials

1. Unique VM Name: Always provide a unique name for the virtual machine to be created in the oVirt environment.

2. Check oVirt Engine Status: 

Ensure that the oVirt Engine status is good and that the engine is up.

Use the following command to check the engine status on the oVirt Engine (self-hosted) machine:

 hosted-engine --vm-status

          Example output:

     Host host1.india.domain.com (id: 1) status

     Host ID                            : 1

     Host timestamp              : 241871

     Score                                : 3400

     Engine status                   : {"vm": "up", "health": "good", "detail": "Up"}

     Hostname                         : example.india.domain.com

     Local maintenance           : False

     stopped                             : False

     crc32                                  : 099bd52f

     conf_on_shared_storage  : True

     local_conf_timestamp      : 241874

     Status up-to-date              : True

     Extra metadata (valid at timestamp):

             metadata_parse_version=1

             metadata_feature_version=1

             timestamp=241871 (Mon Jan 15 11:12:26 2024)

             host-id=1

             score=3400

             vm_conf_refresh_time=241874 (Mon Jan 15 11:12:28 2024)

             conf_on_shared_storage=True

             maintenance=False

             state=EngineUp

             stopped=False

3. Verify oVirt Engine Console Credentials: Make sure the provided oVirt Engine console credentials are correct and valid.
