It's not too nice to send kill -9 to virt-v2v because it means none of
the at-exit handlers get to run, so it will leave temporary files all
over the place.  It's better to send an ordinary kill signal
(eg. SIGTERM).  If virt-v2v doesn't exit after some grace period,
eg. 30 seconds, then it's a bug, but maybe you could then send
SIGKILL.

This is actually another thing which a temporary systemd unit will
solve for us:
