I have a feeling that 'SD' is not supported in all QEMU's we claim to
work with, though perhaps we've never checked this before when
building the CLI args.
Well, we don't. I haven't found any code that checks for 'SD' in qemu
driver. I can remove it until the time we have a resolution.

Hmm, so that's claiming we don't support any values for
the mode attribute, but we support subsys.
Ouch, yeah. The problem is, I was not setting the correct struct member.
Here's the fix:
