Description

Document process for moving VM to /64 rather than /128.

Importantly: customer should modify their name server config (/etc/resolv.conf) to be as follows:

nameserver 2a0a:e5c0:2:12:0:f0ff:fea9:c451
nameserver 2a0a:e5c0:2:12:0:f0ff:fea9:c45d

Failing to inform them of this will result in their VM being unable to resolve most domains, breaking almost all outgoing internet usage on the VM!

Good point.

Timothee, can you create a new network for VMs with routed networks so that we can again decide on DNS64 in bind by network prefix?

Morris, we will fix it the way that the user does not have to do that manually. Above nameservers are the current solution, but are not 100% perfect, because on reboot the VM will currently overwrite /etc/resolv.conf, if you don't remove the script in /etc/one-context.d/
