I believe for HVM profile  :

vnc=1
vncdisplay=0

and HVM doesn't start as i reported to Stefano at Xen 4.1 Dom0 (3.0.0-5-generic)

This option is for VFB definition PV DomU.   In particular at Xen 4.1 ( 3.0.0-5-generic )
on Ubuntu 11.10 ( oneiric)

1. It doesn't provide only a part of VNC window with alive mouse cursor in case F15 DomU
2. It provides VNC window with dead mouse cursor in case F14 DomU

It was also reported to Stefano in the same thread , when it was in xen-devel

I believe the xl command expects you to use 'vfb' option instead of
the vnc and vncdisplay for 4.1

So:

vfb = [ 'vnc=1, vnclisten=0.0.0.0,vncunused=1']

OOh, so you are using 'xl' under 4.1 and not 'xm'? Well, that should
be no surprise. The 'xl' command under 4.1 was in development so
a lot of stuff simply did not work.

In short: If Xen-unstable or Xen 4.2 - use 'xl'. Else, use 'xm'.
