In order to change cd-roms, you need to detach/re-attach the device for
WinXP to re-read the drive. However I've noticed (at least in xen 3.1)
that you have attach a "dummy" drive before re-attaching the real drive.
Here's what i use from dom0:
/usr/sbin/xm block-configure <domU> file:/xen/foo.iso hdc:cdrom r
/usr/sbin/xm block-configure <domU> phy:/dev/cdrom hdc:cdrom r
where hdc:cdrom is the drive in the hvm config.
