Meh, sorry for complications, I'll try to be much more careful next time.

Perhaps you don't have to hurry up for the fix since we have the rest of
the stack (3 more boxes) that we still have to setup via ansible..  So
there's a chance that we'll break something else :-(.

I mean, because ipv4 addresses (32+ for each hypervisor) aren't available
I'm trying other things.  Qemu port-forwarding to libvirt guests didn't
work for me (but I'll try better), ipv6 guest access did not work either
(I'll retry as well), so perhaps we'll have to try iptables hacks or
setup VPN(s) eventually.  I'm afraid all those configuration tasks aren't
really that trivial to be 100% sure that no mistake happens :-(.
