I have another Debian dom0 runing HVM windows 2003R2 flawlessly. I can mount and unmount CD Even if the VM was *created* without any cdrom.
That's what makes me thinks I have configuration mistake (I have to say that the working dom0 is not up to date and claim for update of linux-imge-2.6.26-2-xen and its modules).

Anyhow, I'll try to see if blank CD is a efficient workaournd. Thanks for this idea.

The only method I found that worked was to ensure the device exists at
boot time, then you can change the CD at any time without a reboot.
Though I also found very strange behaviour within windows if I tried to
'remove' the CD by pointing it to /dev/null.... Perhaps it would be
better to create a "blank cd" ie, an iso file with no files in it to use
as the bootup iso file. This was with windows 2008R2 and debian lenny xen...

PS, the only other option I can think of is you might need to manually
allocate a drive letter in windows before it will show up in My Computer...

Hope this helps...
