I ran into this a few weeks ago too, but had forgotten about it. I just filed
a bug report (http://bugs.centos.org/view.php?id=2027).

You could add a cron job:

  find /var/lib/xen  -maxdepth 1 -type f -mtime +1 | \
  egrep "(vmlinuz|initrd)\." | \
  xargs -r /bin/rm -f

This will delete any files older than 24 hours.
