Get access to every feature and settings libvirt has, and gain full control of your KVM virtual machines, bypassing the hard-coded definitions in OpenNebula. Anton from StorPool will present an extensible add-on to OpenNebula that allows fine-grain control on every feature that libvirt provides. Whether you need to use the latest feature in qemu/libvirt that is not yet supported by OpenNebula, or you need a custom logic to control parameters like queue size, with this add-on, you can make your VMs behave exactly as you need. In this talk, you'll learn how to optimize your KVM virtual machines, bypass the hard-coded definitions in OpenNebula and make your VMs behave exactly as you need.
