My idea is 

try to run the domain from bootable cd (not from image)
and look what happens.

You must determine is the problem related to your image (which you
have converted) or from something else.

When you boot from CD system doesn't concern about
your virtual disk image (but it must exist if you have specified
it in the domU config file).

AFAIK, there is parameter in xend-config.sxp
which regulates what port (or screen number) 
Xen vnc must use.
