Read the pvmove man page.
You should break up the move into lots of smaller pieces using the PE range
syntax. If the data is contiguous, you'll have moved 67%, the largest
of those numbers, and restarted at the beginning every time.
Better to 'divide and conquer' so you get lots of smaller moves that reach 100%.
