Dunno if you need these but here goes..

Some info about the critical devices database here:
http://ca.downloads.xensource.com/products/v2xva/README.txt

"The registry modifications are:

i)  Add the IOEMU emulated PCI device to the Critical Devices Database.  
    The emulated PCI device is used by the XenSource Windows PV drivers.
ii) Add "primary_ide_channel" to the Critical Devices Database.  IOEMU only
    emulates IDE disks, and not SCSI disks.  If a VM has been configured
    with SCSI disks, it may not contain a primary_ide_channel entry in the
    Critical Devices Database.  Absence of this registry entry will cause
    converted Windows VM to not boot up when switched to using an IDE disk."
