Comment 12 for bug 1888256

Hi Slawek,

I think, i started to understand the problem, but still not 100%.

Just to clarify:

If I have an IPv4 and IPv6 subnet in the network, and this v6 subnet has RA Mode: None, the qrouter interface (qr-a6d7ceab-80 in this one) should not get the IPv6 address, and/or should not spawn the radvd process?

How this affect the IPv6 for the end users? (if affects)

Now, the horizon shows an IPv6 address for all instances in this networks (possibly it's just calculated from the MAC, but it's the same what the instance choose) for the users, and also creates ip6tables rules with MAC-IP pairs based on this address (AFAIK) and any other rule from Security Groups

I think, this is because the IPv6 address mode is "slaac" in our setup.

So after patching, the users still got the IPv6 address shown in horizon/CLI to instance, and also the security groups will be working?

If I can get a pre-release test package (in a ppa repository for example), we have a dev environment, where I can test it.

Thanks,
 Peter
