Hello all, I've got a multi-NIC machine on which I am running Centos 6.2. I am trying to have a NIC configured with an IP address but not connected to anything. The reason for this is to create a network currently only used by VM's residing on the machine, with that NIC configured to have an IP address that is a part of that network, with a view of connecting real machines to the same network in the future. How can I implement that? Currently ifup just refuses to bring that NIC up. Thanks. Boris.
