Note: you cannot move VM images between pools (since a single SR cannot be shared amongst more than one pool), and you cannot usually mount current (non-XCP) image repositories on a server inside a pool. One trick to play is to actually copy the contents of the images from the outside to a pre-prepared volume inside an SR, and that pre-prepared VDI should be of the same (or larger), and be of type 'raw'.
