Description of problem:

When /etc/sysconfig/network-scripts contains an ifcfg file corresponding to dialup inteface (in my case, ppp0 for ADSL dialup), and the interface doesn't exist, the system log (/var/log/messages) gets filled with messages like these:

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

libvirtd --version responds 0.8.2. I know it's outdated (so is Fedora 12) but I haven't seen any hint about this being fixed since.

How reproducible: Always.

Steps to Reproduce:
1. Create a dialup interface, but keep it down
2. Run virt-manager with the interface down.
3. Check /var/log/messages
 
Actual results:
A lot of messages.

Expected results:
No messages.
