Just a quick RFE; when we do a pvmove through s-c-lvm. we show a battlestar
galactica baddie type progress bar (moves from left to right and back). That's
not elegant.

Please parse the output of 'lvs -a', as we only allow one move through the GUI
at a time, you can grep for the pvmove line and use the number in the last
column to get how much your progress bar should show.

Kudos to agk for showing me where the progress info can be found.
