Subject: [PATCH] v2v: warn when the guest has direct network interfaces
(RHBZ#1518539)
virt-v2v obviously cannot convert this kind of devices, since they are
specific to the host of the hypervisor. Thus, emit a warning about the
presence of direct network interfaces, so at least this can be noticed
when converting a guest.
(cherry picked from commit 1629ec6a5639cf5e226e80bcee749ae8851b1fae)
