<div dir="ltr"><div><div><div>We seem to have bound our config drive file formats to those used by the operating system we're running, which doesn't seem like the right approach to take.<br><br></div>Firstly, the above format doesn't actually work even for Debian-based systems - if you have a network without ipv6, ipv6 ND will be enabled on the ipv4-only interfaces, which strikes me as wrong. (This is a feature of Linux - ipv4 is enabled on interfaces which are specifically configured with ipv4, but ipv6 is enabled on all interfaces that are brought up.)<br>
<br></div>But more importantly, the above file template only works for Debian-based machines - not Redhat, not Windows, not anything else - and we seem to have made that a feature of Openstack from the relatively early days of file injection. That's not an ipv6 only thing but a general statement. It seems wrong to have to extend Openstack's config drive injection for every OS that might come along, so is there a way we can make this work without tying the two things together? Are we expecting the cloud-init code in whatever OS to parse and understand this file format, or are they supposed to use other information? In general, what would the recommendation be for someone using a VM where this config format is not native?<br>

<br><font face="sans-serif">Currently Neutron/Nova code has supported
the static IPv6 injection, but there is no tempest scenario coverage to
support IPv6 injection test case. So I finished the test case and run the
it successfully in my local environment, and already submitted the code-review

</font><font face="sans-serif">but the community Jenkins env has
not supported IPv6 and there are still a few pre-requisites setup below
if running the test case correctly, </font>

<br><font face="sans-serif">1. Special Image needed to support IPv6
by using cloud-init, currently the cirros image used by tempest does not
installed cloud-init.</font>

<br><font face="sans-serif">2. Prepare interfaces.template file

<br>
<br><font face="Arial" size="1">So considering these two pre-requisites,
what should be done to enable this patch for IPv6 injection? Should I open
a bug for cirros to enable cloud-init? Or skip the test case because
of this bug ?</font>
