How to bind a physical network device to dom0 or domU only in RHEL5 cobbler deployed systems?

  • 772

I have a physical machine with two nics.

I already have a fully working cobbler server and I am able to deploy a bare metal or dom0 server in a few minutes. My target OS is RHEL5.

My goal is to deploy a dom0 installation in which only eth0 is up and configured (I can already do it now), and a number of domUs that are only bound to the other physical nic, eth1.

I can assign a different IP for each domU if necessary, of course.

Anybody can point out a link to documentation or an idea to accomplish my task?

The reason of my intent is security, dom0 would be only reachable by a management network, while domUs will only live on public network.

Thanks in advance

  1. Create a bridge in the dom0, connect eth1 in the dom0 to that, and then configure the domUs to connect to the bridge as well.

    I found (only now unfortunately) a cobbler doc explaining how to do the job in a cobbler/koan way:

    This is a very good starting point for me, I'm going to implement it.

    The solution arrived from RHEL5 docs for xen libvirt virtualization: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Virtualization_Guide/chap-Virtualization-Pre_Red_Hat_Enterprise_Linux_5.4_Xen_networking.html
