> My VPC VR is incorrectly being assigned ethNone inside (/etc/cloudstack/ips.json) for my eth1 public network interface. If I edit /etc/cloudstack/ips.json and change both occurrences of ethNone to eth1 and restart the VPC then the network works for isolated guest networks attached to the VPC VR and the VR via SNAT. (note: this issue only occurs with the VPC VR not with guest network or guest shared networks).

> Netmask: 255.255.248.0 /21
> eth1 on VPC VR is the Public network interface
> Guest network uses vlan's 300-500 that are trunked into cloudbr1 on the host computer.
> I'm also attaching the /var/log/cloud.log from the VPC VR
> Note: I restarted the VR several times attempting other /etc/network/interfaces changes before I read on how the VPC VR runs scripts to configure the nics, but the final restart had the reflected changes that causes things to work.
> Cloudstack is using KVM hypervisor.
