Thanks to Luke Faraone, who kindly offered his credits at sixxs.net, we
now have a temporary IPv6 subnet in place. Playing with 65536 subnets
of 64bits each is fun! Too much goodness...
Machines in our subnet reachable over IPv6 by their hostnames:
trixbox1.sugarlabs.org (a test VM running on it)
I have not yet asked for reverse delegation of this zone, because for
performance reasons we're going to switch back to the Italian IPv6 POP
when I'll have enough credits to do it.

This is done. Daily, versioned backups of the whole host. I have not
yet a strategy in place for taking consistent snapshots of the guests,
although I'm using qcow2 images explicitly for this purpose.

This is done too, although I encountered a issue trying to boot off md0
which I couldn't solve:
