Hi Jorge, I have two questions: 1) Has anyone optimized nova to work in a HPC environment like you describe? Such as an intelligent scheduler that will generate VMs that consume x percent of a physical machines resources (so you don't end up with one machine with two separate Hadoop instances com

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 no

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? I've
