networking options for RHEL 6

I saw this note here:
https://answers.launchpad.net/nova/+question/151316


"FlatNetwork does not work with redhat, and requires a lot of manual setup."

Is this correct? What's the recommended networking option for RHEL 6? If
someone successfully configured a RHEL setup, could you please share
your nova.conf? I am running cactus and was able to spawn an instance
but having problems figuring out the networking bridge part.

thanks.

networking options for RHEL 6

Update:

I was able to spawn an instance and log into it. But I think I am still
bit confused about the network bridging issue. The instance spawned on
the controller instead on the compute nodes. Here's what I have:


# euca-describe-instances
RESERVATION r-lzhlpj0j myproject default
INSTANCE i-00000008 ami-00000003 192.168.0.3 192.168.0.3 running
sharif.pem 0 m1.tiny 2011-08-04T15:54:38Z mycluster

# ssh 192.168.0.3
root at 192.168.0.3's password:

# nova-manage network list
network           netmask         start address   DNS
192.168.0.0/25     255.255.255.128 192.168.0.3     None


nova.conf:
       
- --network_manager = nova.network.manager.FlatManager
- --public_interface=eth1

my eth1 is public interface and eth0 is private.

This is my bridge setting (I added eth1 to the bridge by "brctl addif
br100 eth1"):
       
# brctl show
bridge name bridge id STP enabled interfaces
br100 8000.e41f13229a8c no eth1
                                                        vlan100
                                                        vnet0
