Jan Kiszka is the -net user maintainer, I have CCed him.
I'm not aware of work to add IPv6 support to slirp. Someone would have
to step up and submit patches :).
You can still do unprivileged IPv6 networking with external DHCPv6, etc
software:
$ qemu -netdev socket,id=socket0,listen=127.0.0.1:1234 \
-device virtio-net-pci,netdev=socket0
The socket netdev tunnels traffic over a TCP or UDP socket. For TCP it
prefixes each packet with the big-endian uint32_t length. For UDP no
length header is necessary because packet boundaries are preserved.
You could write your own code or find something that can speak with
QEMU's -netdev socket.
