Hello, Cloudstackers :) I would like to offer you a topic to discuss and share your experience:
Does any of you tried to arrange host`s power control and link it to the cloud workload? The idea is to automate hosts switch on / switch off depend of current workload and number of VMs running. It should be possible to control current workload of the hosts and demand for additional resources to proactive start of shutdown the hypervisors and save energy, environment and and our money. All out-of-the-band features is already here https://cwiki.apache.org/confluence/display/CLOUDSTACK/Out-of-band+Management+for+CloudStack and most of the hypervisors (XEN and ESXi at least) can be controlled remotely with no issue What do you think? Regards, Konstantin
