It should be fixed my last patches.
The default gw with RA is still buggy for me.

I wonder if after 8.1 release, we shouldn't also implement static
configuration (through cloudinit for qemu  or directly with lxc).

Personnaly, I'm running vms with multiple ipv6 nics, with differents
static routes, and I'm really not sure It's possible to implement it
with RA.

As ipam/dhcp methods are now splitted, it should be easy to implement.
Maybe implement slaac for ipv6 too.

I think this should be defined at vnet or zone level
(static|dhcp|slaac) to avoid ips conflict.  

Then, the currently lxc gui (static/slaac/dhcp) or qemu cloudinit, the
options should be greyout. (and inherit/forced from the vnet/zone

This avoid to have 1 vm configured with static, 1 other with slaac and
1 other with dhcp with potential conflict.
