      If you create a VM from a template and select Boot from CD, the VM fails to boot and the error unsupported configuration: SATA is not supported with this QEMU binary is logged. This occurs because the CD-ROM is automatically mounted as a SATA device, which is not supported on s390x architecture.

      Description of problem:

      When creating a rhel-9 VM from template, if you enable the "Boot from CD" option, the CDROM will get attached via SATA, which is not supported.
Furthermore when going to the storage options in the WebUI, the virtio option is greyed out.

      Version-Release number of selected component (if applicable):

      4.18

      How reproducible:

      Always

      Steps to Reproduce:

      1. Create RHEL 9 VM from template
2. Select "Boot from CD"
3.

      Actual results:

      VM does not start, as SATA is not supported on s390x.
The log shows:
unsupported configuration: SATA is not supported with this QEMU binary

      Expected results:

      VM starts, as CDROM is mounted with a supported driver

      Additional info:

      Changing the interface to scsi works.
