Title:
  nova boot operation with servers greater then 63 characters don't get
  DHCP address

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  If a server with greater then 63 characters is attempted to be booted,
  the servers will boot but fail to obtain DHCP addresses with nova
  networking and neutron.  dnsmsq is fully configured for the full
  server name, however, Linux has a 64 character hostname limit.

  [sdake@bigiron ~]$ getconf HOST_NAME_MAX
  64

  Recommend a nova exception if a server greater then 63 characters is
  created so the user is aware of the problem at the api level rather
  then wondering why their vm doesn't appear to work.
