Re: [Openstack] Memory quota in nova-compute nodes.

In Essex, you can use 'reserved_host_memory_mb' with the ZoneManager to reserve a certain amount of memory per host. I'm working with Essex milestone 2 and I don't get it to work. I set the parameter on every compute node. root@os-compute2:~# grep memory /etc/nova/nova.conf

Hi! I would like to know if it's possible to configure quota in each nova-compute node. For example, I set up a new hardware with 8 GB of memory and install the nova-compute, but I wish only 4 GB of memory are used (dedicated to nova-compute). Is it possible? If so, how can I configure that?

Hum, I'm just studying and understanding the ccgroups to try this with libvirt and kvm (all nodes are linux here). My case is a test that can be very useful for us. We have about 150 computers spread over the LAN. These computers are desktops and notebook underutilized. So, our test scenario is
