  Problem Description
  =================================
  When using a config-drive to provide meta-data to cloud-init on ubuntu (for Linux guest running in KVM for z Systems) we get a check_instance_id() error whenever we soft reboot after the (successful) initial boot.

  The error shows:

  [    5.283203] cloud-init[1637]: Cloud-init v. 0.7.7 running 'init-local' at Sat, 23 Apr 2016 00:50:58 +0000. Up 5.25 seconds.

  [FAILED] Failed to start Initial cloud-init job (pre-networking).

  
  The failure of the init-local pre-networking does seem to lead to a boot up delay as cloud-init tries to search for networking outside of the already saved networking data.   

  Otherwise the error is purely cosmetic as later init modules find (or
  let existing IP configuration take over) and bring up the correct
  interfaces.

  The original problem was found outside of openstack with stand-alone
  cloud-config iso images.  But have been able to reproduce the problem
  within an openstack ICM environment.

  Team has had some success getting around the problem by patching the
  check_instance_id function in /usr/lib/python3/dist-
  packages/cloudinit/sources/DataSourceConfigDrive.py so that it
  accepted an extra argument, ex:

  ubuntu@markvercd:~$ sudo cat check_instance_id.patch

  Machine Type = KVM guest on a z13 (2827-732) LPAR 

  Steps to Reproduce
  =============================
   1) set up ubuntu guest image with cloud-init
  2) pass in iso image with cloud-config data in cdrom device
  3) boot up successfully with cloud-config data
  4) attempt a soft reboot.
