Comment 2 for bug 1538134

no it didn`t changed.

We are running ubuntu, I believe this is what setup_interfaces left for me:
`ls -la /etc/network/` many files like "orig.interfaces.301115153401" but they are with same configuration

so I just reproduced it, what I have:
reboot compute node (ubuntu 14.04) with `reboot` command.
compute node boots but control node can`t find it - vrouter-agent log - http://pastebin.com/pmsujnxj
