This option works (worked) by passing the caller's display and
xauthority through xm and xend to qemu. qemu then connects to it
later. This is a very remarkable way of going about things. Its
security properties are problematic from several points of view.
I had assumed that because it was so strange no-one would be using it,
so I deliberately dropped that change. Evidently I was wrong. If
this is a feature that is seriously used then I could reinstate it but
I think it should come with a health warning.
A better place to implement this would be xm or some higher level
tool, I think, but that wouldn't be sensible at this stage of the
release cycle.

For now, if you turn off the vncviewer option it will work. If there
is demand I'll look into cross-porting this feature (on Monday,
probably).
