Yeah, that is known not to work.

What I usually do:
- make sure the XP image has IDE drivers installed
- create a new virtual harddisk, partition it for windows and set the
boot flag active
- copy data with ntfsclone
- run ntfsreloc (bundled on sysrescuecd, or you can compile your own)
to adjust filesystem geometry for a NTFS partition on the new

You should then be able to use it on Xen if you use the same ACPI and
APIC settings as whatever you had on vmware.
