Doc Text: |
Previously, when the data plane was in use, changing the target image of a virtual SCSI CD device caused the guest to terminate unexpectedly with a core dump. With this update, the virtio-scsi bus rejects SCSI CDs when the data plane is active, which prevents the crash from occurring. Note that this is a temporary solution, and a full fix to make the data plane and SCSI CD compatible will be provided in the future.
