So basically, my question is, how does openstack actually manage ram allocation?
Will it ever take back the unused ram of a guest process? Can I force it to take
back that ram?
I don't think nova will automatically reclaim memory.
I'm pretty sure that if you have CONF.libvirt.mem_stats_period_seconds set
(which it is by default) then you can manually tell libvirt to reclaim some
memory via the "virsh setmem" command.
