During Full VM recovery, new disk creation or attachment to the created VM failed.

1. Incompatibility with the target disk configuration selected from the BDR UI for new disk creation/attachment.

2. Insufficient space or permissions in the chosen storage domain for the new disk creation.

3. Special characters in the disk name.

4. Connection to oVirt engine failure.

5. Authentication failure of oVirt Engine console credentials.

1. Verify Disk Configuration Parameters:

1. Ensure that the correct parameters are chosen for new disk creation, including Allocation Policy, Interface, Storage Domain, and Disk Profile.

2. Check Storage Domain:

1. Confirm that the appropriate storage domain is selected and has sufficient space and proper permissions.
2. Ensure the connectivity of the respective storage domain.
   

3. Avoid Special Characters in Disk Name:

1. Do not use special characters when adding the new disk name.
   

4. Check oVirt Engine Status:

1. Ensure that the oVirt Engine status is good and that the engine is up.
2. 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

5. Verify oVirt Engine Console Credentials:

1. Ensure the provided oVirt Engine console credentials are correct and valid.
