KVM network config in CentOS 6.6

[LyleRyan]

I built a CentOS 6.6 server choosing the "Virtual Host" option at installation time. This seemed to build the bridge for me, and a Centos 6.6 VM using default networking can get traffic in and out just fine. But I still don't understand....

ifconfig shows:
- eth0 , with the real IP for the host's nic
- virbr0 , the bridge itself, I guess, with an IP of 192.168.122.1
- virbr0-nic , the host-side of the bridge, I'm thinking; virbr0 and virbr0-nic have the same MAC address
- vnet0 , the VM-side of the bridge, I'm guessing; different MAC address than the previous 2

Do I have the right idea on what these devices are?

And where are the config files for them? I thought I would see at least a /etc/sysconfig/network-scripts/ifcfg-br0 file. All that's there is the ifcfg-eth0 file. Maybe some XML somewhere, managed by the brctl utility?

Bonus question: Why is KVM config so confusing? All the tutorials, howto's, and even doc set seem to give different ways to go about configuring KVM. I'd think the RHEL 6 doc set would be all I need, but I'm not so sure.

Thanks for any advice....Lyle

You're set up for a NAT network.
