I've sent out the notice when I branch out for IPv6, said it would
need a template. I stated so again when check in for 4.1 branch. And I
opened the bug for fixing this issue in 4.1. Thanks to Rohit, we
started discussion [3]. Everything looks fine.

But this thing still happened. Bug changed to 4.1 fix version, the
issue raised by QA at last minute.

I don't know how loud should I speak if we need a template for IPv6 in
4.1. Seems nobody cares.

I don't think the thing would depends on if my statement is strong or confident.

I don't think we should let systemvm run apt-get things.

According to what I observed in the community, I think probably it's
right that people not quite interested in ipv6.

Probably we just revert the UI for 4.1 branch, and make API usable
with updated template.
