Weird.  Could you please post your domain config file?

From the real CD, presumably?  You want something like:

disk = [ 'file:/tmp/winxp.iso,hdc:cdrom,r', ... ]

in your disk list.  This'll make hdc in the guest be an emulated CD-ROM drive 
holding the contents of your ISO file.

There's a boot order variable in the config, you'll need "c" to be first if 
it's going to boot off the hard drive.  e.g.

boot = "cda"

will try initially to boot from the hard drive, fall back to the CD-ROM drive 
if that fails, and finally try to boot from the emulated floppy drive.

Those issues shouldn't be a issue with your particular version.

FC6 shipped with a Xen based on 3.0.3.  Xen 3.0.1 to 3.0.4 are feature 
releases not just bugfixes as the numbers imply.  I have the impression that 
3.0.4 and above has better support for running HVM guests, so you may find 
Windows works better if you upgrade.  3.1 is what *would* have been called 
3.0.5 in the old numbering scheme; you might want to consider upgrading to 
that, although there are probably still some bugs to find in the new features 
of that release :-)

Cheers,
Mark
