I'll give that a try.  I don't know if that's it, though.  I have another
computer that has Vista installed and when I boot that one in debug mode it
doesn't wait for a remote debugger.

I think in Windows XP, when you're in debug mode, Windows waits for the
remote debugger to connect before continuing the boot process. So maybe your
remote debugger did not connect yet?

As you may know, you need to enable serial driver in HVM domU config file,
then forward this console to a TCP port (possibly), then connect to this TCP
port from your remote debugging machine, then use another software there to
show this tcp connection as a serial port to Windows. Then you'll connect to
this serial port from Windbg and you can type (g) to continue the boot
process on your DomU.

        I have successfully installed and booted Vista Ultimate in Xen
(3.1.2, on
        Fedora Core 8).  However, I want to use a kernel debugger (windbg)
which
        requires me to boot Vista in debug mode.  To boot into debug mode, I
hold F8 
        and select the appropriate option.  This, however, doesn't work.
Vista
        doesn't boot and all I get is a big black window.
        
        I've also tried modifying the boot options with the command "bcdedit
-debug 
        on" but that doesn't work either.
        
        I'm pretty new to Xen so I'm not sure what output/files would be
useful to
        include here.
        
        Thanks for any help!
