> We have setup cloudstack with advanced networking. We have a network created 172.16.24.0/23, called news preprod. This has a number of vms created under it. When we initially set this up, we noticed that the router we created with 4 ethernet interfaces. This was unexpected, but didn't seem to be effecting the running of the router, so we didn't worry about it. The interfaces were: eth0 172.16.24.14, eth1 169.254.1.91, and both eth2 and eth2 were given the external ip (xxx.xxx.245.59). We investigated why we were getting 2 externals, but couldn't figure it out. We also configured the router to have a redundant, with keepalived. They were working fine.
> Now I needed to add another external ip to the network. Did that, and restarted the network. I now have 8 (eight) eth interfaces. The new external ip is NOT one of them. Heres the ifconfig output:

> The cloudstack management browser still shows the router as only supposed to have 3 nics.
> The agent log on the physical host has nothing in it (I was tailing that log when I did this, as I would have thought that the agent has to create the devices for the vm to get them).
> I have attached the management log from just before to just after. (Time of change was 9:39am). I do not know why the router timestamp is not the same as the host. 
> I have also attached the log of the router restart.
> The physical server is Centos 6.4, and all the vms that we have created are Centos 6.4. KVM is the hypervisor.
