Title:
  Large user data (>8k) prevents creation of VMs

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  This affects all openstack versions AFAIK, but we saw this with Folsom
  (EPEL openstack-nova-api-2012.2.2-1.el6).

  We have an application that sends in large amounts of userdata via the
  URI.  However, eventlet.wsgi.server() has url_length_limit=8192 as a
  default argument.  (Since it was coupled with bug 1054501, it was not
  obvious from the server side what was going on, but the client was
  returning HTTP Error 414).

  Here's a simple fix against master.

  (edited to include a better patch):
