Fool network interface into thinking it is connected
I have a second NIC in my machine that I am using to create a subnet for a cluster of Xen VMs on my machine. Nothing really needs to be connected to this interface as no traffic ever needs to leave the subnet (all the Xen VMs are on the same physical machine). However, if I don't have a cable connected, the interface thinks it can't do anything and won't try to route any packets. The setup works fine when a cable is connected. Any suggestions always appreciated!
