Description of problem: Fedora 22 Workstation and group Virtualization installed, but there's no network option for the VM.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora 22
2. dnf group install Virtualization 
3. Create new VM in virt-manager
At virt-manager new vm step 5 of 5, Network selection is set to No virtual networks available.
NAT option should be available by default.
These items were installed.
Rebooting resolves this. The option "Virtual network 'default': NAT" is available in that same pop-up menu now. But it's still unexpected I have to reboot to get this option seeing as it's "the default". So I have to reboot by default? Weird UX.

Problem is it requires a libvirtd restart, its a known issue
