Subject Re: Regarding Shrinking of Volume

If you're asking what I think, it would be RAW.  The pool type would be
CLVM, though.  This is probably a better solution, as we likely want to
grow the cases that the automated tests run. If we're testing KVM at all it
is trivial to set up an LVM volume group as a storage pool to test against.
