description:
- "DataVolumes are a way to automate importing virtual machine disks onto pvcs during the virtual machine's
launch flow. Without using a DataVolume, users have to prepare a pvc with a disk image before assigning
it to a VM or VMI manifest. With a DataVolume, both the pvc creation and import is automated on behalf of the user."
