Berrange on KVM with routed IPv6

Saw a blog post by Dan that explains how to set up IPv6 on KVM hosts with routed virtual networks. I pretty much did everything like he suggests except I used the "Rich Jones" prefix fd2d:acfb:74cc::/48 instead of Dan's 2000:dead:beef::/48. One thing that bothers me with all this is the need to have statics at the upstream router and the ICMP redirects. It would be totally kickass if Dan came up with some kind of "standard" Zebra config or found some other way to make it all automatic. The sticking point is that in case of OSPF you still need to configure the upstream router, and in a non-obvious way, too. Static routes are well understood. Back in the 90s, we just ran routed everywhere, which required zero administration, but that's not IPv6 compatible.

Honestly, the more I look at challenges that virtual hosts introduce, the more I think that bridged networking should be the default in libvirt. The only reason I personally do not do it is that historically Linux bridging was a mess full of bugs, plus it changed in incompatible ways every 7 to 10 kernel releases. This may be not the case anymore, but I am too set in my ways.
