You don't need it on the client, but on the source and destination.

I guess I wasn't quite sure of your setup.  I will _also_ caution you
that if your source and destination hosts are not using identical qemu
versions, you risk the migration failing for other reasons (for example,
you cannot migrate between Fedora and CentOS hosts, because the two
distros have slightly diverged on the set of patches applied to qemu).

There's your problem.  Debian isn't auto-installing a 'default' pool,
and without a pool, libvirt can't clone the file from the source.
