There's a lot of redundancy here.  What about keeping the guest types
together, like the following?

---
### x86/PVH

    Status, domU: Supported
    Status, dom0: Experimental

[description]

Note also that dom0 support requires IOMMU or VT-d hardware.

Sure. I wasn't aware that we could use 'Status, XXX:'. Somehow I
thought this won't be processed correctly, but there are bunch of
entries using this format already.

Let me send v2.

Thanks, Roger.

Well at the moment there isn't any processing.  If it turns out to be
too difficult to process as it is, then we'll have to figure something
else out; but as you say, there are already dozens of other entries that
will need to be changed as well.
