We'll try and go through and add some language to the wiki, but you can

Can you describe how you're assigning those addresses and the VM
configuration in question? Is this a SmartOS zone, a KVM instance,
something else? While we don't have automated ways of assigning IPv6
addresses in vmadm, it should still be possible to set this and I don't
recall any changes in that part of the stack from us or upstream.

Thanks,
