[GitHub] [cloudstack] Pearl1594 opened a new pull request, #6296: xen: Fix volume snapshot deletion when it has child snapshots
Pearl1594 opened a new pull request, #6296:
URL: https://github.com/apache/cloudstack/pull/6296
### Description
This PR fixes the constant test failure noticed on test_list_ids_parameter.py on xenserver :
https://github.com/apache/cloudstack/pull/5811#issuecomment-1104053583
The reason for the failure is that on 4.17, when attempting to delete a snapshot that has child snapshots, it fails deletion of the snapshot altogether. In addition to this, an NPE occurs when displaying the details of the child snapshot due to incorrect snapshot id used to get the details.
```

Review Comment:
Actually Yes , however, it's usage comes into play only cleanup logic :
1. where in it decides whether to cleanup the snapshot on the secondary store or not
2. When there are snapshots in destroyed state and the garbage collector kicks in, so the impact of this hasn't been big.
