Pull request overview
Fixes snapshot failures for ONTAP-backed volumes that are created-and-attached to running VMs in a single step by ensuring the volume’s image format is set consistently (KVM → QCOW2) during ONTAP volume creation.
Changes:
- Set
VolumeVO.formatduringcreateAsync()for both iSCSI and NFS3 ONTAP-managed volumes based on the pool hypervisor. - Add unit-test stubbing for
StoragePool.getHypervisor()to support the new format-resolution logic.

Description
Fix snapshot failure for CloudStack volumes attached to running VMs on ONTAP primary storage (both NFS3 and iSCSI protocols).
This PR...
When a volume was created and attached to a running VM in a single step,by enabling create on storage and choose the storage pool tag the volume format was not being set correctly. The format is now determined by the hypervisor type (KVM → QCOW2) in volumeapiserviceimpl via [getImageFormatByHypervisor(HypervisorType] mirroring the [getSupportedImageFormatForCluster] in VolumeOrchestrator file.

How Has This Been Tested?
Tested on a dev setup against these scenarios:
Scenario A — Attach data disk to running VM, then snapshot
Scenario B — Attach volume to root-disk-only VM, then snapshot
scenarios-C-create a volume on storage pool but not attach to any vm
Screenshots (if appropriate):
snapshots for when cs volume is attached to NFS and ISCSI instance that has both root and data disk and create on storage enabled:


verifying on ontap and db:



snapshots for when cs volume is attached to NFS and ISCSI instance that has only root and also case when they are not attached to any instance and create on storage enabled:


How did you try to break this feature and the system with this change?
