I have deployed guest ubuntu 13.04 & installed cloud-init 0.7.2 on it. But it seems it has a bug setting Network address

auto lo eth0 (this line is missing)

 address 172.29.250.13

 netmask 255.255.255.0

 gateway 172.29.250.1

so it is not brining up the eth0

I tried this through API

Kindly help for work around.
