Hi,
I have an existing fedora14 system with two interfaces and several
virtual interfaces (as in eth0:0, etc). They are currently configured
to not be controlled by NetworkManager, but just standard network
services.
I've recently started working with libvirtd, so I also have a virbr0
interface as well that has its own network and is masquerading the
networking for the single KVM instance I have running.
I would now like to create another instance that is not masqueraded,
but instead uses another virtual interface, such as eth0:1, which is
an Internet-addressable IP address. When I try to do this,
virt-manager seems to still configure it using NAT.
I think the right way to do this is to convert the eth* instances to
instead use a real bridge, correct? How can I do this?
Below is the output from ifconfig on my system:

Thanks for any ideas.
