ksmd seem to be CPU hungry when virtual machine is running.
+KSM is a memory-saving de-duplication feature, enabled by CONFIG_KSM=y,
+added to the Linux kernel in 2.6.32. See mm/ksm.c for its implementation,
+and http://lwn.net/Articles/306704/ and http://lwn.net/Articles/330589/
I’ve disabled it for now, we’ll see how everything runs afterwords…
