When the user doesn't pass a kernel with QEMU's "-kernel" switch, the firmware sees a zero-sized kernel blob via the QemuFwCfgItemKernelSize key; there's no way to distinguish "no kernel" from "zero sized kernel". In both cases TryRunningQemuKernel() proceeds as far as gBS->LoadImage(), which then rejects the zero sized synthetic file with EFI_UNSUPPORTED. This is known and works fully as expected; however we should rather catch the much more frequent "no kernel" case earlier, in order to avoid the EFI_D_ERROR message TryRunningQemuKernel: LoadImage(): Unsupported which is arguably meaningless noise for the "no kernel" case.
