[PATCH 03/11] qemuDomainValidateStorageSource: Add validation of 'encryption' support
Peter Krempa

Fri Apr 22 15:31:47 UTC 2022
Reject encryption requests for unsupported image format types.
Add negative test for the rejected cases as well as modify
'disk-network-rbd-encryption' case to validate that with librbd
encryption the format doesn matter.
