The question assumes there's such a thing as a *standalone [Linux] 
kernel module*.

This is not a given, and according to all lawyers the FSF has 
talked to, a fiction.  Or so the FSF states in the last paragraph 
of the ‘What Constitutes the Entire Work?’ section of 
<https://www.fsf.org/licensing/zfs-and-linux>.

(Sorry for the link!  I couldn't resist ;-)

My understanding was (and still is) that this is specific to 
CDDL+GPL only, not CDDL+LGPL, so distributing a dynamically linked 
libvirt with ZFS support is allowed.

Kind regards,
