Public bug reported:
When I use nova's /etc/network/interfaces file injection via configdisk and set
up by cloud-init, I end up with a not working /etc/network/interfaces like this
one (notice the missing line feed and the "address None") :
----
# Injected by Nova on instance boot
#
# 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
auto eth0
iface eth0 inet static
address 10.1.0.14
netmask 255.255.0.0
broadcast 10.1.255.255
gateway 10.1.0.1
iface eth0 inet6 static
address None
netmask Noneauto eth1
iface eth1 inet static
address None
netmask None
broadcast None
iface eth1 inet6 static
address XXXX:XXXX:XXXX:XXXX::c
netmask 64
----
I use two interfaces for two different networks one v4 only on eth0 and
one v6 only on eth1.
I also attached a patch that corrects both issues.
About the second issue, since the patched version checks for IPv6
address existence, it might be possible to delete the use_ipv6 check.
