Hi all,

I've got a simple two-node cluster, each with three NICs running CentOS 5 (64bit). Each node has this configuration:

eth0 - Internal network (IPMI on this NIC)
eth1 - DRBD link
eth2 - Internet-facing NIC, dom0 has no IP

I've built a simple VM that uses 'xenbr0' and 'xenbr2' as the VM's 'eth0' and 'eth1', respectively. I've set a static, public IP to domU's eth1 (xenbr2 -> peth2) but I can't ping it from a workstation nor can the domU ping out. I know that the network itself (outside the server) is setup right as I tested the static IP from that cable earlier on a test machine.

Could someone hit me with a clue-stick as to what I might be doing wrong? Let me know if any logs or config files are helpful.
