SolusVM's IPv6 not working on Ubuntu? Try this

solusvm-ubuntu-ipv6-isoinstall.md

Why won't IPv6 work on Ubuntu? (when doing an ISO install - KVM templates should work properly)

1. Run Reconfigure Networking in SolusVM

2. Combine the inet6 and inet blocks, i.e.

from

# Generated by SolusVM

 auto lo
  iface lo inet loopback

 auto ens3
iface ens3 inet static
   address 173.xx.xx.xxx
   gateway 173.xx.xx.xxx
   netmask 255.255.255.xxx
   dns-nameservers 8.8.8.8 8.8.4.4

iface ens3 inet6 static
   address 2607:ff48:xxx:xxx::2
   netmask 64
   gateway 2607:ff48:xxx:xxx::1
   up ip addr add 2607:ff48:xxx:xxx::10/64 dev ens3

Works automagically :)
