[Bug 1153626] [NEW] Multiple Interfaces and IPs not detected in AWS VPC

[Michael Hale]

Public bug reported:

I booted a c1.medium with ami-3fec7956, 2 interfaces and 2 IPs per
interface. I expected the 4 IPs to be configured on the instance when I
logged in, however only the primary interface had a single IP assigned.

DHCP does not seem to support multiple IPs per interface so the alias
IPs will probably need to be statically assigned based on the EC2 meta-
data API (http://169.254.169.254/latest/meta-data/).

Additionally since network interfaces, and their IPs, can be moved
between running instances in VPC, any solution should detect hot-plug
events and not just setup things at boot time.
