something went wrong during boot, check /var/log/xen/qemu*.log
(a qemu*.log is created for each Windows/HVM guest)

I would also try file: instead of tap:aio for the disks, even though
file: is supposed to be deprecated, sometimes it still works
better in some situations.

What version of Xen are you working with?

setting the vnc options to 0 and sdl to 1 might be something
to try

Also if it happens to be Xen 3.3, replacing the vncconsole
line with vncviewer="yes" would be another thing to try.

Most of the time, when it quits write away it is a problem
with either the disk image or the cdrom.

Hope that helps.
