Bug 865805

Description of problem:
This error was encountered when a user ran Image Factory in a virtual machine, unaware that this was not supported. This is the error that appeard in the logs:

While we may not support building in VMs, the error doesn't make it very clear what is wrong. It would be fantastic if the log included a more readable error, indicating that it failed to connect to libvirt (?) and that the user should make sure it is running, and that they are not inside of a virtual machine.


Version-Release number of selected component (if applicable):
imagefactory-1.1.1-1.fc17.noarch


Steps to Reproduce:
1. Attempt to build an image inside a VM


Actual results:
The error message, while correct, doesn't really give the user an indication of what might be wrong.


Expected results:
The error message indicates to the user what is wrong and how it might be remedied.
