Description Josep 'Pep' Turro Mauri 2013-11-07 10:04:45 UTC

It should be possible to make specific reservations for HA vms to make sure that we always have enough spare capacity to start the HA VMs if N hosts fail.

This we can do in a basic way with the pluggable scheduler but it would be better if there was a dedicated feature in the engine.
