Something as coarse-grained as 'xm block-detach/block-attach' would probably
work in this situation, as the CD device is unmounted during the install
process when waiting for next CD to be inserted.

Better would be to notify media-change events and size changes without
needing vbd detach, but that isn't supported for PV VBDs yet.
