Title:
  clients need to try multiple IPs when connecting to hosts

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Since most (all?) of the api daemons are unable to listen on and IPv6
  socket problems arise in IPv6 environments. If a server is listening
  on IPv4 and its hostname has both IPv4 and IPv6 addresses associated
  with it then a client attempting to connect to that host *by name*
  will fail as IPv6 is the default protocol to use if it is available.

  This is aggravating for a period of time while various open stack
  clients report "connection refused" but a telnet session (or other
  simple test client) to a specific api port "works." Eg:

  tims@horizon >telnet os-api1 8776
  Trying 2607:f088:0:2:5054:ff:fe26:801...
  Trying 192.168.2.100...
  Connected to os-api1.
  Escape character is '^]'.
  ^]
  telnet> quit
  Connection closed.
