Bug 1047350

Description of problem:
EPEL did it to us again there was an update to cobbler from 2.2 to 2.4 from the server side it doesn't seam to be a big problem so far, but the syntax for koan seems to have changed. this specifically causes a problem with visualization and visualization platform



Version-Release number of selected component (if applicable):
any version of spacewalk >= 1.8 with koan 2.4.x

How reproducible:
install the Virtualization or Virtualization Platform package group on a spacewalk managed host.

stop osad on the virtualization host so you can manually trigger rhn_check latter to view the output

entitle the box for Virtualization or Virtualization Platform in spacewalk
go to Virtualization -> Provisioning for the host.

attempt to create a VM

from the command line on the virtualization host run rhn_check


Actual results:
the build will fail and rhn_check will give you output like this
