For non-boot devices, loopback works. You only need the hardware if
are testing boot time capabilities (which, admittedly, is the far more
important aspect of testing for this package).
And if you don't have spare systems with more than one drive to play
around with then kvm virtualization comes to the rescue when testing
pretty much any md or dm issue, possibly even including multipath.
