Feature Overview (aka. Goal Summary)  

Add a new VolumeSnapshotClass (non default) that includes the snapshot-type: images parameters this allows the KubeVirt use case of creating VMs from "Golden Images" (templates saved as snapshots), as users cannot spin up more than 6 VMs per hour from a single template.

Goals (aka. expected user outcomes)

GCP PD CSI operator will create a new VolumeSnapshotClass

Requirements (aka. Acceptance Criteria):

The new VolumeSnapshotClass is created by default by the operator (but non default), it includes the snapshot-type: images parameter.

The OCP virt team should verify that the provided VolumeSnapshotClass meets their requirements

Use Cases (Optional):

Questions to Answer (Optional):

Need to sync with the OCP virt team to decide if there is anything specific to do besides creating the VolumeSnapshotClass e.g annotation

Out of Scope

This is for GCP PD CSI only

Background

Default snap restoration is limited to 6/h which is not compatible with virt use cases where several VMs can be created from the same "image" 

Customer Considerations

Need to make sure it doesn't confuse non virt customers

Documentation Considerations

Add note in the docs about this new VolumeSnapshotClass, what is it meant for

Interoperability Considerations

GCP only
