Public bug reported: Description of problem: Configuring metadata network-interfaces with "iface eth2 inet6 static" breaks all networking on cloud-init instance. This only works when configuring a sub interface.
The following breaks networking: ~~~ auto eth2 iface eth2 inet static address 192.168.0.166 network services netmask 255.255.0.0 broadcast 192.168.255.255 gateway 192.168.0.1 iface eth2 inet6 static address 2001::166 gateway 2001::1 hwaddress aa:aa:aa:bb:bb:bb ~~~ According to https://wiki.debian.org/NetworkConfiguration , this should work, though: +++ If you're configuring it manually then something like this will set the default gateway (network, broadcast and gateway are optional): auto eth0 iface eth0 inet static address 192.0.2.7 netmask 255.255.255.0 gateway 192.0.2.254 If you want to add an IPv6 address, too, append something like: iface eth0 inet6 static address 2001:db8::c0ca:1eaf netmask 64 gateway 2001:db8::1ead:ed:beef +++ And https://manpages.debian.org/jessie/ifupdown/interfaces.5.en.html +++ Options are usually indented for clarity (as in the example above) but are not required to be. +++ The following works correctly: ~~~ iface eth2 inet static address 192.168.0.166 network services netmask 255.255.0.0 broadcast 192.168.255.255 gateway 192.168.0.1 auto eth2:0 iface eth2:0 inet6 static address 2001::166 gateway 2001::1 hwaddress aa:aa:aa:bb:bb:bb ~~~ Additional info: result working: Working instance: ./sosreport-20180125-075718/svc-1-lvsrouter/var/log/cloud-init-output.log ~~~ Cloud-init v. 0.7.9 running 'init-local' at Thu, 25 Jan 2018 07:48:44 +0000.
