This is not 100% reproducible. Sometimes the server comes up this way and other
times it comes up just as you'd expect with em2 properly configured and up.
This is a Quantal install on a Intel server.
Upon initial bootup of a server after provisioning via orchestra server I have no network device configured. My /etc/network/interfaces file looks like:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto rename3
iface rename3 inet dhcp
This server has em1, em2, em3 and em4:
