  Hi,

Why keep virtio-blk in DXEFV but drop virtio-scsi?

> -INF  MdeModulePkg/Bus/Scsi/ScsiBusDxe/ScsiBusDxe.inf
> -INF  MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDiskDxe.inf

These are needed too for virtio-scsi.

> +INF  FatPkg/EnhancedFatDxe/Fat.inf
> +INF  ShellPkg/Application/Shell/Shell.inf

Why add the shell to DXEFV?  Shouldn't this go to NCCFV?

Also please wrap this into '!if $(BUILD_SHELL) == TRUE' for
consistency with the other ovmf build variants.

take care,
  Gerd
