Bridges with physical ethernet interfaces attached are listed. Bridges with a dummy interface attached are not. I'm not sure why, but I think libvirt gets its information from HAL and HAL doesn't see these dummy interfaces. I need to set up a system, which allows a non-root user to create a virtual machine using some graphical interface. And the most important part is: we need a secure network configuration with strict packet filtering and custom DHCP setup. It doesn't seem to be possible that libvirt uses my manually defined network bridges without manual editing the guests XML files.
