[OSR-devel] Bridged Interfaces

[Gordan B. <go...@bo...>]

Hi,

I'm trying to configure a cluster for KVM virtualization with bridged 
networking, which might cause a problem or two so I wanted to get some 
feedback before I actually do it.

Specifically, KVM bridged networking requires a bridged network device, 
which I'm not sure can be set up in cluster.conf at the moment.

Assuming one NIC, eth0, it would require something like the following in 
the non-cluster setup:

# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:11:22:33:44:55
ONBOOT=yes
BRIDGE=br0

# cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
TYPE=Bridge
BOOTPROTO=static
IPADDR=10.11.12.13
NETMASK=255.0.0.0
GATEWAY=10.255.255.254
ONBOOT=yes

I think br0 can stay in real-root (as opposed to initroot), but eth0 
would need to be set up in initroot for node ID purposes, which would, 
presumably, require it to come up as the bridge device. Is that doable?

The only other thing I can think of is to add another NIC in the machine 
to work out the node id from. That would work as a work-around, but it's 
a bit of a bodge.

Any thoughts on this?
