Description Assaf Muller 2013-07-24 12:20:09 UTC
Description of problem:
In 3.2 VDSM talked to ksm via ksmtuned. 3.3 VDSM uses MOM to talk to ksm, but upgrading VDSM from 3.2 to 3.3 doesn't disable ksmtuned. That means that VDSM may send conflicting instructions to KSM as both ksmtuned and MOM are active. In systemd we marked VDSM as conflicting with ksmtuned, so something similar needs to happen with systemV.

Additionally, there is a nontrivial amount of code in VDSM with the
