• the improved Live-Migration performance - now virtual machines move from a host to a host much quicker, besides customization the politician of VM is available during migration.
• loading of images through GIU - earlier images of virtual machines needed to be loaded from the command line, now it can be done via the web portal. Also libvirt VM can be imported using the virt-v2v utility.
• support of containers - appeared support of machines from guest Atomic OS OS for which there is also information on the containers Docker which in them are started.
• oVirt Node is the ready virtual machine with oVirt management tools based on the Cockpit panel.
• API v4 is more convenient now, works quicker and also oVirt include Ruby SDK now.
• an opportunity to configure the settings transferred when loading a core on hosts from the web console.
• Stateful VM Pool are pools of virtual machines in which they are started with preserving of the previous status. This status remains also when changing the owner of VM.
• an opportunity to unroll hosts from the web portal through Hosted Engine.
• possibility of removal of a parent template (at the same time the oldest of child becomes basic).
• use of the VGA driver instead of Cirrus for the VNC console.
