Description of problem:

  Kickstarting virtual guest on machine registered
  to Spacewalk 1.6 on RHEL6.2 fails with "Could not find Cobbler".

Version-Release number of selected component (if applicable):

  cobbler-2.0.7-15.el6sat.noarch

How reproducible: deterministic(?).

Steps to Reproduce:

  1. register client, add virtualization entitlemnent,
  1.5 setup machine so it has running libvirtd and stuff...
  2. schedule kickstart of virtual guest,
  3. run rhn_check (-vvvvv...) on client.
  
Actual results:

  Kickstarting fails with traceback(s) (<fqd> replaced):

D: do_call kickstart_guest.initiate('localhost', '<fqd>:1:asdfjklo5.0', 'qemu', 25, 'asdfjklo5.0', 1024, 1, 3, 'br0', '/var/lib/libvirt/images/asdfjklo5.0', ' '){'cache_only': None}
