Ah, I guess we have to distinguish the two...

Hope about an optional: vbd:/emu: prefix (or similar) on the second part of 
the triplet for a disk?  The default (for non VMX domains) could be "vbd" so 
existing behaviour would remain the same.

If / when we move over to using "xvd" for VBDs I guess that could subsume this 
functionality (might still need it for non Linux guests, tho).

Thoughts?

Cheers,
Mark
