Cloud images only bring up one NIC

I've noticed with both Ubuntu cloud images and CirrOS images that, even though I provide multiple vnics when creating a VM in Nova, they only bring up the first interface.

After booting, I'm able to confirm by checking the /etc/network/interfaces file, where only lo and eth0 are defined. This seems to be hard-coded for some reason.

When I add eth1, I'm able to bring it up, but this seems counterintuitive to the idea of spinning up ready-to-use VMs.

Is there any way whatsoever to get these to bring up each NIC instead of just one?
