Yes, we're adding new stuff faster than we're documenting it properly.

Well, the XML in the VMX-2-XML tests is the output generated by
libvirt, so it's correct that all those files use the new syntax. In
case of the XML-2-VMX tests the XML files are the input, and here all
tests still use the old way to define the SCSI controller model.

Actually, I should add XML-2-VMX tests that use the new syntax and I
should add some negative tests to make sure disk address verification
works correct. But that's stuff for an additional patch.

Thanks, pushed.
