That's what I intend to read more thoroughly, though I already skimmed
through it while I set it up. HA simply didn't work... Softdog behaving
erraticly, corosync reporting a quorate cluster (and multicast behaving
properly) while resource manager was unable to start, let alone protect
or migrate vms..

I will investigate, and report (unless I find I did something wrong). I
also tried to explicitly separate the NIC for the filer from the
management/cluster one, but it didn't work (and I can't say I believe
it's actually being checked, but it's mentionned in the docs ;))

Also, I won't insist much, but LXC live migration is a requirement for a
proper upgrade plan, as it's working for OpenVZ, and it's not possible
for us to lose that feature.

Cheers,
