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!
