Hi Kouya,

   I'm curious, what did you use for the filesystem to do a windows live
migration?  Or maybe you did a localhost migration?  I applied this, but
I seem to only be able to migrate an HVM domain once.  I started it on
server A, did a successful live migration to server B, then tried to do
another live migration back to server A, and got this:

Are you able to migrate more than once?  Thanks,
