what i saw ... xen-create-image creates the 80GB file ... in Megabytes 
81920.

example:
freespace on /home like 100000MB ...
at 99% ->> freespace 18080 then at 100% it jumps back to 100000MB 
freespace.... wtf
creating the file i think the xen-create-image is using "dd"
df -hm is shown correctly used space till the file create process "dd" 
comes to 100% it jumps back as it has never be used space

thats really strange
