  I initially created a symlink pointing /usr/lib/python2.7/dist-packages/bin/nova-dhcpbridge -> /usr/bin/nova-dhcpbridge
  which fixed the problem, setting bindir=/usr/bin in nova.conf is a cleaner workaround.

  I do not know if the default nova.conf has bindir specified, but it
  strikes me that /usr/bin is a much better default bindir than
  /var/lib/python2.7/dist-packages/bin...
