Yup, this is a missing feature in libguestfs when using the libvirt
backend (instead of the default which is to run qemu directly). In
Fedora 18, we're using the non-default libvirt backend, so
consequently this missing feature breaks virt-v2v.

The simplest workaround is to switch back to the default backend. Do:

export LIBGUESTFS_ATTACH_METHOD=appliance

before running virt-v2v.
