[Users] addNetwork error trying to add management bridge.

I've got the following errors: 2012-Feb-04, 20:07:46 Host ovirtnode.grims.com installation failed. Please refer to log files for further details.. 2012-Feb-04, 20:07:46 Failed to install Host ovirtnode.grims.com. Step: SetNetworking; Details: addNetwork error trying to add management bridge. Previous to this the node went through the step of installing various packages. This is an FC16/64bit/VMX capable host. I've been wondering for some time if install is RHEL specific. In any case 2 questions: What causes this error? What logs does this log speak of? Thanks in advance I've had a lot of fun using your tool so far :)
