Possible, but not easy. Your best bet would PROBABLY be to start here
http://www.vmware.com/products/converter/
to convert your machine to vmware disk format and then go here
http://ian.blenke.com/vmware/vmdk/xen/hvm/qemu/vmware_to_xen_hvm.html
to convert it to Xen HVM disk image.

Which makes it even harder :)
Note that even if your conversion process is succesful, XP will prompt 
you to activate your license key again due to hardware change. So in 
general, I'd say don't bother. Install a new XP HVM instead.

This is wrong. If you're using LVM from HVM domU storage, then the LVM 
will be the disk, not the partition. In short, if you go the dd-way, it 
should be "if=/dev/sda" instead of "if=/dev/sda1". In your case this 
still won't work though, because your VG is located on sda. Again, your 
best bet is probably using the two-step approach above.
