Hi, currently ksmd is a single process and is thus bound to one core. This leads to some scaling problems such as: If you got a lot of vms on one host with huge amounts of ram you can observe that the cpu usage by ksmd goes easily to 100%. I wonder if ksmd could not be split up in child/worker threads, thus enabling higher density of vms on one host. or can this just be tweaked by altering values in /etc/ksmtuned.conf ? What do you think? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
