This sounds like you don't have a storage pool running on the directory
/var/lib/libvirt/images (Fedora pre-installs a 'default' storage pool at
this location, but I suspect that your gentoo machine did not).  To
confirm, compare the output of these commands between your two boxes:

virsh pool-list
virsh pool-info default

Not a missing image, so much as a missing storage pool.  Libvirt can
only clone files that live in a storage pool, and we haven't yet wired
it up to be smart enough to auto-instantiate a transient pool around the
directory of all files that are not already in a persistent pool
(although I someday want to get to that point).

Again, probably a case of your distro automatically installing a
'default' pool.
