Mapping multiple KubeVirt CSI volume snapshot classes

You can map multiple volume snapshot classes to the hosted cluster by assigning them to a specific group. The infrastructure storage class and the volume snapshot class are compatible with each other only if they belong to a same group.

Procedure

To map multiple volume snapshot classes to the hosted cluster, use the group option when creating a hosted cluster, as shown in the following example:
```
$ hcp create cluster kubevirt \
  --name my-hosted-cluster \
  --node-pool-replicas 2 \
  --pull-secret /user/name/pullsecret \
  --memory 8Gi \
  --cores 2 \
  --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \
  --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \
  --infra-storage-class-mapping=<infrastructure_storage_class>/<hosted_storage_class>,group=<group_name> \
  --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class>,group=<group_name> \
  --infra-volumesnapshot-class-mapping=<infrastructure_volume_snapshot_class>/<hosted_volume_snapshot_class>,group=<group_name>
```
- --name specifies the name of your hosted cluster.
- --node-pool-replicas specifies the worker count.
- --pull-secret specifies the path to your pull secret.
- --memory specifies a value for memory.
- --cores specifies a value for CPU.
- --infra-storage-class-mapping specifies the storage classes. Replace <infrastructure_storage_class> with the storage class in the infrastructure cluster, <hosted_storage_class> with the storage class in the hosted cluster, and <group_name> with the group name. For example, infra-storage-class-mygroup/hosted-storage-class-mygroup,group=mygroup and infra-storage-class-mymap/hosted-storage-class-mymap,group=mymap.
- --infra-volumesnapshot-class-mapping specifies the volume snapshot classes. Replace <infrastructure_volume_snapshot_class> with the volume snapshot class in the infrastructure cluster and <hosted_volume_snapshot_class> with the volume snapshot class in the hosted cluster. For example, infra-vol-snap-mygroup/hosted-vol-snap-mygroup,group=mygroup and infra-vol-snap-mymap/hosted-vol-snap-mymap,group=mymap.
