[ovirt-devel] oVirt 3.6 new feature: NUMA aware KSM support

[David Maroshi]

Greetings users and developers,

Just put up a feature page for the "NUMA aware KSM support";

In summary,
===========
The KSM service is optimizing shared memory pages across all NUMA nodes. The consequences is: a shared memory pages (controlled by KSM) to be read from many CPUs across NUMA nodes. Hence degrading (could totally eliminate) the NUMA performance gain. The optimal behavior is for KSM feature to optimize memory usage per NUMA nodes. This feature is implemented in KSM since RHEL 6.5. We want to introduce a new feature to oVirt that will allow host administrator to control NUMA aware KSM policy. 

You're welcome to review the feature page:

The feature page is responding to RFE 
https://bugzilla.redhat.com/show_bug.cgi?id=840114

Your comments appreciated.

Thanks
Joy and happiness
Dudi
