Thanks, Corey. How does the lan_config_program in lan.conf work? I couldn't find an example in the OpenIPMI-2.0.21 tarball. Our central controller expects each node's ipmi module to dhcp for an address. I'm trying to decide if I need to run dhcpc on the interface that ipmi_sim runs on. Can I just bind ipmi_sim to an interface and let it dhcp for its address? If not, how does it work with lan_config_program?
FYI, In our setup, we have two networks for ipmi and data. One control node is connected to both networks and provides dhcp controller node1 node2 ... IPMI eth0 ----- ipmi0 ---- ipmi0 DATA eth1 ----- eth0 ----- eth0 I'm using veth pairs with one end in a bridge for the ipmi interfaces and tap devices for qemu simulating the nodes. -- Noel On Thu, Apr 23, 2015 at 2:42 PM, Corey Minyard <miny...@acm.org> wrote: > On 04/22/2015 07:25 PM, Noel Burton-Krahn wrote: > > OK, I've build qemu and openipmi.
