How to setup libvirt with ipv6?

I presume that is the problem as I have no internet connection on the vms and from the below investigation.

Ipv4 routing just works out the box for libvirt so does ipv6 require manual intervention to setup?

My new 4g dongle seems to use ipv6 as when I do

Code:

ip route

there are only the virbr interfaces left showing. I do however have internet access and when I do

Code:

ip addr show

the dongle interface looks like a v6 ip.

So how does one setup the virtual networks of libvirt for ipv6?

I am far from fluent in understanding networking and usually scrape by following step-by-step tutorials.

Is this SO thread what I am looking for?

You need to add the "-6" flag for showing routes (but not for ip6 addresses, for some reason).

Code:

ip -c -6 route show

I prefer bridging, and use radvd for the ip6 side of things.
