How did you create it? If you created a spare file (with seek), it
will not work, what I use to create virtual disk images/partitions:

dd if=/dev/zero of=virtualdisk.img bs=1024 count=2000

(this will create a 2GB file)

When you get this error, can you switch to the Dom0 and paste the
output of running "xenstore-ls -fp"?
