This feature (selectively migrating block devices during live migration) is
missing for us right now.  I know it's an old thread, but as far as I know,
this hasn't been fixed.  In the more recent thread I see that there are
thoughts to re-work this code (pre-copy vs. post-copy), but doesn't the
interface need to be fixed anyway?  Where are the known issues with block
migration documented?

Thanks,
