Unfortunately I no longer have those logs. *However* last night I powered down my node and engine. Last night engine would at least come up. Now when I boot up my engine I get the same error. So my guess is that the shmmax setting isn't being configured in a persistent fashion somehow, or is somehow reverting. My most recent setup log is here (I hate to send large logs to lists): https://dl.dropboxusercontent.com/u/35965416/ovirt-engine-setup-201311031...
