Following conversation with rgolan This is the planned actions solving this RFE. 1. Use NOTT11 host (Numa capable) to enable kernels 'boolean knob /sys/kernel/mm/ksm/merge_nodes'. Test its configuration at runtime. 1.2 Design programmatic solution to config 'boolean knob /sys/kernel/mm/ksm/merge_nodes' with vdsm deploy mechanism. 2. Append 'boolean knob /sys/kernel/mm/ksm/merge_nodes' boolean constant to Ovirt Engine config mechanism. 3. Program automatic configuration of 'boolean knob /sys/kernel/mm/ksm/merge_nodes' on vdsm deploy mechanism. 4. Test automatic configuration of 'boolean knob /sys/kernel/mm/ksm/merge_nodes' on vdsm deploy mechanism. 5. Program a unit test for 'boolean knob /sys/kernel/mm/ksm/merge_nodes' effective install. Please comment.
- an /etc/modprobe.d/ovirt-ksm.conf should be created if not already exist (maybe under different name) instead of altering /proc at runtime as the host-deploy is rebooting the host. - special care for oVirt Node - by design oVirt Node config is stateless so need to make sure that is persisted - consult with Fabian Deutsch fdeutsch
