Virtual machine (VM) affinity allows you to define whether the VMs are run on the same host (positive affinity), or run separately on different hosts (negative affinity).
It is recommended to enable negative affinity for VMs associated with the CommServe and the Control node to enhance performance. VM affinity must be set using the Virtualization Manager, which can be accessed by typing the following URL in a Web Browser:
https://<Control Host Name>/ovirt-engine
For example:
http://mycontrolhost.mydomian.com/ovirt-engine
